Motorcycle and Scooter appreciation

In all seriousness- if I wanted (just for the sake of argument) to have a full and frank exchange of views with someone on a motorcycle, and suspect that they will simply bugger off, is it as simple as grab key, turn to left, pull?

That's a bit of an incendiary move, don't be surprised if you get a bloke in a full suit of armour going UFC on your arse.
