Guerilla Pot Hole Spraying?

No, all you need is this:

It's a one-stop shop. TfL pass the details on to the local highway authorities. Works very well.

(Tsk, tsk, TB, short memory? ;) )

I used this recently to report that massive crater at New Oxford St/Museum St, and I noticed it's been filled now.

I described it as a bad accident waiting to happen - if my report was what got it sorted, it leaves me wondering whether TFL's motivation is fear of accidents, or fear of litigation.

Either way, who cares. The road's a bit safer now.
