Yes I would, and those days are getting closer and closer as we have our first 3D printed supercar now:

@raceprouk they have to load in all of their obtrusive ads and pop-overs. Because they want to annoy their users.

The automobile industry has been relatively stagnant for the past several decades.
Did someone just emerge from a timepod? I don't think the average Joe could get around 50mpg in a hybrid, or low to mid 20's in a V8 developing 500+hp "several decades" ago.
Also, 0-60 is a crappy performance metric which is heavily affected by tire type and heavily biased in favor of AWD platforms. Give us a 1/4 mile timeslip and video, please. Especially when some magazines assume 1 foot of rollout for their 0-60 times...
Speaking of tires, I wonder what they plan to put on this thing? I can't imagine the average consumer is going to be happy putting 100 treadwear R comps on all four corners, as pretty much all street tires would be sketchy with this kind of power.

Average Joe? Probably not. John Lingenfelter and Reeves Callaway did though, and on a car putting out a lot more than 500hp.

1988 Callaway Sledgehammer Corvette This Sledgehammer reached 254.76 mph at the Transportation Research Center (TRC) in Ohio and became the world’s fastest street-legal car for some time. It was built up by Reeves Callaway in Connecticut as an example of what was possible with the new ZR1 and and...
I am not finding any sources that mention its mileage, but I seem to recall that it got mid 20's in fuel mileage as they drove it to the track and back.

3D printing car components isn't actually all that new: top-flight motorsport's been there for several years already. It's just taken this long for it to become commercially viable for road car use.

The vehicle, called the Blade, has 1/3 the emissions of an electric car
So 1/3 of zero? I guess it's still zero, but why not say 1/10000000000 then?

I'm assuming you knew that I meant production cars. But if we're including the aftermarket, that easily
to 1000hp today.I am not finding any sources that mention its mileage, but I seem to recall that it got mid 20's in fuel mileage as they drove it to the track and back.
That seems plausible. Let's see it do that while carrying fifty million airbags and other safety and emissions equipment required in recent model years.

Sure, if you only look at the tailpipe. Pay no attention to all of the trucks moving those raw materials and components around.

Depends on your part of the planet.
Here (Quebec), 96.8% of our electricity is from hydro and 2.9% from other renewable sources (wind, solar).

I recall an interesting course I took in undergraduate in which we'd take current events, familiarize ourselves with the engineering background, then crunch the numbers in order to articulate an informed opinion. The professor was a former head of the National Academy of Sciences and the university wanted him so bad they basically gave him a whole department just for the one course.
If I recall correctly, at least given the electricity sources used by the United States at that time, electric cars were 10 times worse for the environment than regular cars. Now, if we were like France (fucking GOD FORBID) and 98% of our electricity was nuclear (and we reprocessed nuclear waste like we should), then we'd be getting somewhere.

Most of the places that don't have rivers have other alternatives, such as solar and possibly wind. There's a lot of other options than burning coal.

There's also this thing known as a Power Grid. All the generating plants dump their stuff in and we sip it out (NO!! Not that electron! That's a dirty coal one - I only want solar ones!)

Calm days with no wind.That's why you don't use just one power generation source, and have some sort of energy storage scheme. (The latter also makes commercial sense; the value of each generated megawatt-hour varies widely through the day.) A regional or national grid can also help.
Solar's big advantage in the US is that maximum power usage is due to AC, and that maxes out when it is sunny (unsurprisingly). Wind is more suitable in places where there's a reasonably reliable windflow, so offshore deployments tend to be better as there's a lot less trickiness without all that land in the way; offshore wind farms can get huge, but I don't know much about siting issues for them in the US. I do know that the UK doesn't really use much hydropower despite having pretty good rainfall, as the geology and geomorphology are frequently unsuitable for big dams (and the places that are suitable tend to be used for drinking water supply instead).
More generally speaking, I'm a fan of looking at what works in a particular locale. I'm even relatively happy with saying that fossil fuels can be the best option in some places (though coal tends to be so filthy that it's not an option that ought to be usually favoured anyway, even ignoring any CO2 production).

We really need a commercially viable way to turn atmospheric CO₂ and green electricity and/or waste heat into hydrocarbons.

Quite apart from the old-fashioned approach of growing trees, there are people working on adapting algae so that they produce hydrocarbons directly. It's just annoyingly difficult to do, given that you want the algae to keep on doing it and not die from the cytotoxicity.

Genius. So let's make a car powered by burning trees as an excuse to plant more trees!
