I look forward to buying my first used electric car in five to eight years. Probably a Leaf. Should be lots of hobbyists at that point rebuilding their own battery packs by hand.
Top Gear reviews hardly make a difference anyway, I think anyone who has watched even a few episodes knows they exaggerate negatives for entertainment value almost constantly; the Tesla was hardly their only "victim" in this regard.
Basically, they imagined the worst that could possibly happen, but when it didn't happen, they pretended that it did anyway.
This is kind of like saying "we reviewed your iPhone app. Because apps can crash, we wrote a review describing all the way your app crashing ruined various real-life activities we had, even though your app never actually crashed."
Second, as another reply points out, they did not really point out genuine shortcomings but rather fabricated events and used strawmen. If you analyse existing usage of sports cars, you will probably find the vast majority are used for short and medium distance driving on the road, not cross-continent or highly intensive race track driving. Hence the design and marketing of the Tesla.
As far as I'm concerned, the Top Gear guys are hucksters.
This is a show that will [jokingly] talk about how much they don't like a new $250,000+ hyper car.
