!hazard add-on

[Tingle]

A lot of people use !roadblock in conjunction with !hazard so as to increase their visibility to cars approaching from behind, however, the tyres that are spawned obviously serve little purpose in actually protecting the scene from further damage (from those who ignore caution and hazard signs).

A good idea would be to have a barrier spawn behind the car that's called !hazard, so as to decrease the chances of further damage occurring to other vehicles as a result of the hazard being ignored.

It would be similar to how the tyre stacks appear behind a car when you do '!roadblock 2', but this time with a barrier and perhaps with a gap of a few metres or so behind the car.

Clarification: The barrier would be used in times of accidents, not to stop suspects.
