> if you like cars and road trips enough to watch GT or Top Gear you probably care a lot about being able to make road trips.
I don't know about that. They do it just to shit on EV's. (Disclaimer: I own an EV, but also like and watch Grand Tour). It's an entertainment show. They're not about objective analysis. It's the crank-call-radio-morning-show model applied to cars.
Their complaints about the i3 was low range (needing multiple recharges) and weak power (when range extended).
They could have used something like a Vauxhall Ampera, which is actually designed for the road-trip route they ran (all electric in London, powerful gas range extender for freeway driving at 80+mph).
They could have used a pure-EV car that actually had decent range like a Renault Zoe, which would have only needed a single recharge stop to make their entire trip, even driving at 70mph the whole time.
But they didn't. They didn't use a fair car to test, because then it would have been less funny.
