@dcon Yeah, if you see a snowplow ahead, slow down stay behind. Keep enough distance, possibly even the 2 seconds that are commonly recommended for all situations, since the salt they are spraying behind them is bad for your car.
There is still a lot of sand layed down as well, it isn't all just salts.

@Gustav I can remember starting a car like that...
I did that once as a test to check automatic transmission stuff. Doing it at highway speeds was probably not recommended, but science!
AFAIK, it doesn't usually work for automatic transmissions. It's not a problem for manuals, though. I used to have one which I'd somewhat routinely (anti-patterns thread is ) shut the ignition off at highway speed and coast with the clutch in to save gas. When I slowed down too much (to ~the speed limit), I'd release the clutch, the engine would start, and I'd accelerate back up to cruising speed and repeat.
save gas as if accelerating back up to speed didn't use more of it

@loopback0 I used to do that on the right kind of hill, except without actually turning the engine off. If gravity's going to help me save fuel, why not?
The Glenluce bypass, westbound, was particularly suitable for this, being a pretty good incline down. Or for putting your foot down and seeing just how much your car wanted to break the speed limit by. (They've adjusted the painting of the road so it doesn't look so fast now.) It was also a section of road where you really wanted to overtake, having just endured miles of being stuck behind some slow idiot towing a caravan yet unable to pass because the curves on the road meant you never had a sight line worth a damn...

Correct! Mostly because the system isn't able to shift in if it's not already there.

Noooo, you shift to neutral, don't burn out the clutch!

Throttle drag.
Gasoline, i.e. spark-ignited, engines are more efficient alternating between off and full throttle than at quarter throttle all the time. It does not matter for diesels, and I believe most new gasoline engines have “ultra-lean burn” for efficiency at low throttle. And of course you don't want to turn the engine off in anything with power steering and power brakes, which includes everything that does not have a veteran status by now.

I know that as engine braking. Downhill, leave the engine in a higher gear which has two main effects:
- Use the engine's internal friction as braking force. This reduces the amount of braking your brakes need to do, reducing risk of brakes over heating
- It keeps the engine running above idle speed without needing to use any gas.
Apparently some people's intuition leads them to use both the brake and the clutch when going downhill, meaning all the braking effort goes on your brakes while you're spending gas to keep the engine at idle.
My new car is a hybrid with computer-controlled gearbox. In the same downhill situation it will stop the engine and use regenerative braking.

That's something else. I was talking about going down a hill steep enough that you could maintain highway speeds with the gearbox disengaged.
Or you can keep things engaged and see just how fast you can really go.
Engine breaking is something that's more useful close to home. We have quite a few hills round here (this not being ), especially ones with road junctions at the bottom. Using engine breaking to stop the vehicle running away helps because you can approach the junction at a comfortable speed for the traffic level. Though I find I use the brakes more with an automatic; I just never really warmed to the force-lower-gear option that my current car has.
-
I'm not sure if it's easier to break your engine in low or high gear.
But braking via the engine is done by keeping the gearbox in low gear, not high.

Depends on the car and gearbox though - I've had automatics that disengage the gearbox and coast when you lift off, so I've needed the brakes going down hills, and some that don't.
My current daily car, and the previous one, is a pretend-hybrid so uses the regen braking as well as engine braking so I use the brakes a lot less.

Mine tries to be smart. It will disengage for some period of time and then shift down if above some arbitrary speed.
Naturally I treat my vehicle as if it were manual so this doesn't make much a difference overall.

I had one where I specifically "downshifted" the automatic (no longer in automatic mode). The car decided otherwise and shifted anyways.

the stunt was planned and was filmed for a television program. Which program is involved is still secret for the time being.

Unless you know that you're strong enough to brake anyway, and aren't planning to slow down to speeds where power steering matters.
Back in my university/army days, the last kilometer of dirt road to my parents' house was nearly all a downward incline. There were couple of bluffs in it, but not enough to really slow the car down. Plus the last 10-15 meters of driveway were upward. I used to turn off the engine when that kilometer started, and coast all the way to the parking spot.

@Applied-Mediocrity Part of that kilometer was used in Neste Rally's Moksi special stage some years, yes. But the race route takes a sharp turn about 600m in, while my parents' home is further straight downhill.
Not the hill on that particular clip though. If it were, they would slow down already, on account of said turn. *cough* wussies *cough*

@BernieTheBernie if you were in a car you'd have had space to carry a chainsaw.

-
@Zerosquare Over here, there would typically be a partial barrier (passable on the left side) after the last intersection and a full barrier over the entire road close to the actual problem site. But then here it's not very mountainous and there are almost guaranteed to be residences between the two barriers which need to remain reachable.
-
The sheriff’s statement claims that the driver and possible occupants had fled before the authorities arrived to the scene.
About an hour after the crash, the owner of the vehicle called 911 to report that the car had been stolen sometime in the early morning hours. The owner’s residence was approximately five miles away from the crash scene.
Yup. Stolen. Uh huh.

@HardwareGeek My car has sign detection. Just informational. The only reason it's any good at all is that it also uses mapping data. And at least around here it does occasionally happen that it sees a sign that does not belong to the road you're on.
Automatic hard braking while you're doing 100 on the highway because the car saw a 30 sign on a parallel road is downright dangerous.

If you drive as fast as your car lets you, even if's obviously unsafe, instead of limiting yourself to what's safe, that's a bigger problem that technology really can't fix.
-
@HardwareGeek The other problem around here is that they're particularly cheap about placing end-of-restriction signs. They strongly prefer to just let the restriction end implicitly at the next side road. And side roads are rather harder to detect than signs.

Status: these speed limits are getting rather ridiculous. Below is an artistic recreation of one encountered earlier today
Maybe it’s meant to be 9 in octal

https://www.youtube.com/watch?v=SxPAro4rB1kThe systems to have such speed limits have been implemented already, and like i said when they were being built, the politicians are now getting giddy with getting all up into people's lives.

Fortunately at least you seem to have held the capture device relatively level, which helps.

Correct my lack of RTFM, but speed limiters do not typically control braking, only eliminating acceleration past a given set point?
-
@Tsaukpaetra And usually pushing the pedal to the metal will suppress the limiter. That doesn't make things much safer though.

@loopback0 And that matters why? As long as the important systems like braking, steering and lights work reliably and the structure remains solid enough, temporary repairs to the skin, with permanent characteristics of otherwise, don't affect the safety of the vehicle.

Without having read TFA, it could be trying to disguise a car that had been involved in a hit-and-run or other illegal activity. It's a piss-poor disguise, but most criminals aren't very bright.
