to be fair, id get through that easily. I have three motorbikes, not a car. Not a problem. or, people could buy much thinner cars? dont need to own such wide ones really. How about a quad bike with a shed roof? or a peel p50? theyd get through there.
I'd use a horn. Swearing and shouting is natural, but it can also lose you concentration. Also that the motorcyclist blasting past you when the lights changed (around 0:08).. had you wobbled there would have almost certainly been a collision and it would have been their fault.
Tip: Report him to the police for a suspected "hate crime" and I can guarantee you'll get a response. Why? Because they are told to prioritize these reports and are always going on and on about how they won't tolerate hate etc etc. This is the system Parliament created - this is the system they get.
Any failure to respond to your complain (record all calls and keep all correspondence ) should also be met with a complaint which you should then, if need be, take to a higher level. If the driver of that vehicle wants to act like some moron from an overseas slum-hole then that's his problem not your's and he has no right to be racist.
Amazing VW Polo driver, can easily tell he passed first time
