Oh indeed. Both the examples they supplied broke down on the Top Gear test
track. To the point where the test had to be abandoned.

A replacement battery pack costs about $30,000. Like all Li-ion, mustn't
be allowed to run flat. Which means in practice the car has to have
regular use and left on charge when not. Great if you wish to leave it at
the airport when going off on holiday.

Of course like all batteries, a better one is just around the corner. And
has been since lead acid were invented. Yet lead acid are still in use...
