I'm surprised we haven't seen more of that yet.

You also forgot to solve plethora of environmental concerns related to building electric vehicles. Then there's the geo-political concerns. Where are all those rare earth elements going to come from for the motors?

That's why it's a ginormous bait n switch.

They're gonna hook everyone on EV, abandon ICE, then they're gonna not be able to build cars for anyone but the ultra rich.

Does anyone know if cobalt will continue to be an essential battery component for the foreseeable future? Seems to be a debated topic and there are some cobalt investments floating around.

Think about the average 10-15 year old car someone on the lower rungs of the economic ladder would buy. How many 2011 model electric car aren't approaching the end of the useful life of their battery packs? Would a 2011 Honda Accord need a new engine given the same use? The poor are really going to be screwed by a major switch to EV. With a little maintenance you could drive a 2006 Ford Escape until the end of time, but a 15 year old EV will probably be in the junk yard.

That brings another unintended consequence, what're the economic and environmental costs associated with 'prematurely' scrapping these EVs going to be?

You know what would be cool, though ... would be a hybrid built for performance. A gas engine optimized to run efficiently in a narrow range of rpm for max efficiency, charging a moderately sized battery that served more to even out power delivery as needed on demand to a speed control and drive motors. You need a generator, but you can toss the transmission by using the speed control to drive the gears. Make it four motors, each spinning a CV axle, and you can get rid of the differentials, as well. Now you have electric drive and it's efficiencies, with gas tank range. Design it right, you could even switch over to direct generator to motors, if you let the engine rev a bit more. That'd haul ass! And be loud.

They have hybrid supercars already brosnovo.....

Can't they switch out the batteries? I recall Tesla demonstrated switching out the batteries in about 90 seconds.

Tesla to Debut Battery Swapping Stations

Will Rimac offer the option to switch out the batteries on their Nevera? What's the point of paying $2.4 million for a supercar if the batteries can't be replaced?

Tesla shuts down battery swap program in favor of Superchargers, for now

Are you talking about swapping battlers as a method of refueling instead of sitting on a charger, or as a replacement for a tired pack?

The first has a number of technical and economic challenges to overcome to make it viable. The second is an option, but a replacement battery pack is in the $20,000 range. How many people are going to want to invest that into a 15 year old car?

Yes I meant as a replacement for a tired pack. For an expensive car like the Nevera it would be worth it. Perhaps the cost will come down in the future though.

Perhaps, but that will depend on substantially increased production capacity (both assembly facilities and strip mining). Demand is already out stripping supply today.

On the other hand, here's a rebuild kit for a tired 2V:

Their isn't enough cobalt and other materials to make the cars themselves. Think how many batteries they would have to make for a viable swap station to exist in the same numbers as gas stations. Not to mention they would have to standardize battery sizes.
