Believe me when I say, I understand you, I just don’t agree with you.
The point still stands. Also note that Nissan itself says that repeated fast charging of the Leaf's battery will cause it to be unable to hold a full charge. The fast charge option being the 30 minute, 80% charge option which is the fastest you can charge a currently-in-production electric vehicle.
These are the facts and there's no agreeing or disagreeing with them. Top Gear presented them in a clumsy way, but they're still facts.
They didn't mislead the viewer about anything. Did you watch the show? They were very clear about how many miles were left. I fail to see what your problem is, beyond, "they did not promote the things I like, and they focused on issues which I want to ignore."
Edit: upon re-reading what you wrote, it's clear to me that you really don't understand what I'm saying. This isn't about freedom to do whatever they want to prove some point. This is about how a television show is made. Television is produced, deal with it.
