Re: "right of way"
"THE BIGGEST VEHICLE should always have the right of way."
I realise you're probably trolling, but for the benefit of others, and with the caveat that it's a while since I checked...
The only place where "right of way" applies in the UK is at zebra crossings, where pedestrians have right of way over vehicles.
In every other circumstance, "right of way" does not apply. Other rules may have similar effects, e.g. not passing a red traffic light.
