This is true in theory, but in practice I think hybrids are the worst of both worlds. I've had two Toyota Priuses and a Honda Civic Hybrid all of which we drove to around 150,000 miles each. One of our Priuses and the Civic Hybrid needed their hybrid batteries replaced during their lifetime. Not only was this a significant cost but I've got to believe that it negates a lot of the environmental benefits of the vehicle. It's not an uncommon problem either, there are plenty of 3rd parties selling refurbished hybrid battery packs, it's a common enough problem that a whole industry has built up around it. In addition both of our Priuses started burning oil at some point over 100,000 miles. This is a notorious problem with the Prius and there are lots of discussions about the problem in online forums. It certainly ruins any illusion I had about clean emissions from the cars over the course of it's life. I never fail to notice the little puff of grey smoke when behind Priuses at stop lights when the engine starts up again, so much for being the clean air poster child.

We have a Tesla Model 3 now with about 50,000 miles on it, we've only seen about a 2-3% decrease in range so far, if even that. The only maintenance so far has been refilling the washer fluid and we've replaced the tires once. I see no reason why it won't easily go to 150,000+ miles. The difference with the hybrids we have had is night and day, it's not even close. Toyota does not have a winning hand to play here and they know it. They bet on the wrong tech and they are tied down by a dealer network that is dependent on maintenance costs to support them.
