Mr Cooper’s sarcasm does nothing for his argument (letters, July 10). And my examples aren’t ‘hypothetical’, but real-life situations, the ‘single-carriageway’ to which I referred being an A-road (of which there are many hundreds of miles in the UK), not a country lane.

Clearly, Mr Cooper will never understand the concepts of ‘accelerating out of trouble’ or ‘accelerating to avoid trouble’, so there’s no point in continuing this correspondence.

If I encounter a situation requiring a split-second decision: brake or accelerate, I certainly won’t think twice about the latter if it means I (and the other party) will live to see another day. And I’ll most definitely never buy a car with a speed-limiter which will stop me doing this, which is where it all started...
