Just crashed into a Lamborghini!

I tend to prefer making a point whilst passing these kind of drivers by merely making my presence felt by a hard tap to the bonnet/window. This often puts the frighteners up them, forcing them to pay extra attention in the future.

Although I tried to slap the back window of a Rav4 last night, missed and nearly fell off my bike. WAC (what a clumsypoo).
