It was properly weak television and really uneven..
I thought the burning the battery scene was really problematic, once you've shown its actually really hard to set a modern batt on fire. Whats the point of testing to destruction? Sure a big fire ball looks impressive and can go on the trails as "exciting TV". But it's also going to be used out of context to claim EV's are death trap and potentially put people off.
Thought the drag race challenge was pretty weak. A bodged together Beatle was never going to break any records. I guess on the budget front it was a case of "well we already have this car"... It just seemed too arbitrary and uninteresting compared to Martins other "challenge" films - eg human powered flight was really interesting.
The final Clarkson bit about EV's not being ready and 50 mile range... apart from being bollocks is also dangerous disinformation. Martin via C4 has a huge profile - this sort of stuff scares people off from EV. I know its not C4's job to promote EV's - but we are also in a situation climate wise that ICE vehicles need to be replaced as soon as possible and its a public service to encourage people to do that.
