1.) Electric car "spews out" about 80% less CO2 than the best ICE. It does that only when charged from the fossil fuel burning plant. If charged from sun, wind or water it doesn't release CO2 at all.
2.) Electric cars are fun to drive.
3.) It is just a matter of time when the gas cost will shoot up. Venezuela is on verge of collapse, Iraq and Libya are a mess, Nigeria as well, ME population is increasing rapidly while oil revenues are declining. Local government paid people to keep quiet. But as the oil revenues decreased it will be more and more difficult to do so.
4.) We could make better stuff from the hydrocarbons than burning it.
5.) To have cleaner air is a good thing.
6.) To be a coal miner is an unhealthy, dangerous and miserable job. No I take it back, that is no job that is hard work. Installing PV is a job.
That's the thing that HS/et-all aren't getting. CO2 is just one part of what makes EVs so exciting.
They've got gobs of torque that can be controlled with extreme precision(~500W to 600,000W). I challenge anyone to drive a 5klb sedan that can do sub 4 seconds and not enjoy it.
Due to the lack of rotating mass(crankshaft, flywheel, etc) they do better in low traction situations(dirt, snow, rain) than any other car(sub 1ms response time). I can floor our 500hp Tesla in the rain and it doesn't even wiggle.
Much, much less maintenance, in 55k miles I've done: Tires, coolant and windshield wiper fluid.
Better safety(and lower center of gravity which means better handling) due to not needing to pivot an engine under the front seats.
All car subsystems can be run independently(running AC when you get back from the store for instance).
Much lower operating costs(5x less than my previous, 25pmg car).
There's a bunch of people in the local Tesla group who don't care two ways about global warming but like the cars, because they're fantastic cars. Any EV is going to share similar characteristics and is why you'll see adoption continue to grow.
