Tesla cars are so far ahead of the competition that effectively there IS no competition. The latest electric motors in them run at 15% higher speeds making power to weight and effeciency much higher than the competition.
You might give details on efficiency, since it can be measured by various criteria. For an EV, one practical metric is in miles per kW-hr.
According to this source

Tesla is not the top. In fact, it's tied with my Kia Niro! Wow, am I proud!
He is now building batterries for his cars that no longer use rare earths ...
AFAIK, no EV batteries use rare earth metals. Those metals go into things like magnets, not batteries.
and do not catch fire so you can recharge them inside your garage.
Tesla may be working on batteries that are less likely to catch fire, but that's already an insignificant problem. See
<
https://www.motortrend.com/features/you-are-wrong-about-ev-fires> or many other sources.
From <

"In 2023, Sweden’s Authority for Social Protection and Preparedness (MSB) reported just 24 EV car fires in 2022, representing just 0.004% of the country’s 611,000 EVs. For cars running on gasoline or diesel fuel, the fire rate was 0.08%." IOW, liquid fuel cars were 20 times riskier.
Oh, and I've always charged my EV in my garage. My antique motorcycle is a much bigger fire risk, and I don't worry about it.
He is selling cars for $12,000 new without a lot of bells and whistles on them.
Wow. Source? Everyone else seems to think Teslas start at about $40,000.

Not only is he using reusable launche vehicles but he can LAND them which NASA never even thought possible.
Maybe it's no surprise, but I have two friends who were NASA engineers. There was a third but she died several years ago. (Two of the three were cyclists, BTW - that's how we met.) Anyway, one was literally a "rocket scientist" and still does some consulting for NASA and a bit for SpaceX.
He's the one who said NASA did examine re-landing rockets back in the day but decided there was no way it could be done quickly and in a way that was economically feasible. And it may still not be economically feasible. How many rockets has SpaceX wasted in its trial and error development of re-landing?
Keep in mind that computing and computer control have advanced tremendously in recent years. we now have cars that at least partially self drive (mine keeps to lane center automatically), parallel park themselves, and more. Don't blame NASA for not suddenly inventing 2025 computer technology decades ago.
My fucking water bill last month was $100 and that was almost entirely from flushing toilets. That, just 15 years ago wouls have been $10.
Mine arrived yesterday. $26.10 for the month. You need to move out of that hellhole before your water bills break you!
