A disclaimer: 238Pu has a half life of 87 years so it has a higher initial investment. But you only fill it once. You can choose 90Sr which has a half life of 28 years, sure you'll fill it twice (3 times if you're lucky), but you can have a service do it for you. If you're a real cheap skate, or you just dig that refueling station community vibe, you can go for the 210Po which has a half life of a measly 138 days. So you'll only be filling it up about a 2,000 times before you're too feeble to drive.

I looked into rtg and it's interesting. I'm not sure what the cost would be and I would be worried about the radiation possibly leaking.
Yea, it's a quandary when you're trying to power a satellite, where every gram counts. But for a land vehicle, the lead shielding would be more than adequate without a punishing weight increase. It would probably weigh slightly more than a V8 combustion engine. And it would likely never have to be opened for the first owner. After that, it's a matter of what energy source they choose.
Tesla loses $717 million in 2nd quarter. Tesla Loses More Money Than Ever, But Says Profits Are Coming
They did post a profit 3rd quarter $313 million and looks like around the same 4th quarter. $313 million sounds a lot, but still represents only a 2% operating margin, and they will of course come out at a loss for the whole year And all of this of course when they are supposedly expanding. Youd need quarterly profits in the 10s of billions to convince anyone of their longevity
