Wasn’t the same concern with the Toyota Prius when it was first released? Only for all the doubters to be proven wrong by the taxi drivers who kept beating Priuses for decades.

In any case battery failure seems rare but it still is catastrophic and nobody can afford replacement. Hence companies should just provide some sort of warranty / insurance product for the few unlucky folks. Seems like an ideal candidate.

Those old taxi Priuses have had their batteries replaced.

They do.
