Dear prick in the car on the M55 last night,
If you don’t want the truck driver from ‘Duel’ on your rear bumper with their headlights on main beam, then why not try letting them overtake you instead of speeding up when they pull out then slowing down when they pull back in. It got old fast after several aborted overtaking attempts.
As another suggestion, your personalised numberplate alluding to the size of your penis might be better representative of you if you chose to buy something like ‘W4 NKR’. Just a suggestion.
