My biggest disappointment with Top Gear was the Cessna 182 vs Bugatti Veyron race across Europe. It was a very poor and wildly inaccurate reflection on GA. Complete nonsense.
I agree; it was a stupid stunt and a great wasted opportunity to help GA. If May really has a PPL he could have done much much more than a stupid demeaning stunt like that which made GA pilots look like a bunch of incompetent d*ckheads.
I hardly watch it nowadays because it is just a comedy.
