Dozy c**t near dalston junction

um - remember that generally a car braking in front of the car behind would show brake lights, and we don't have any such way of communicating our drop in speed.

Except "mirror, signal, manoevre". Or over-the-shoulder look, in our case.

The times I've had near misses from behind, it's been when I couldn't signal (braking plus steering over rough ground/potholes whilst keeping an eye on oncoming traffic whilst looking for small gap in lorries and cars to turn right in).
