I’d have done exactly as the OP did.
Most people have no idea what’s coming up behind them, only the other day I was going along with a car really close behind as I was doing to biggest crime ever of keeping to the speed limit and behind the car behind me was a Ambulance On blues and twos.
This clown behind hadn’t got a clue the ambo was approaching and I decided to indicate left in the Hope that she would check her mirrors, she then tried coming round me then must have spotted the ambo and swerved in like they do abandoning a car at the end of a police chase.
As we moved off, she started adjusting her interior mirror…..
I had a low car once and there was a fire and the hose was running across the road so had to drive over them ramp things and drop down.
As I approached the hose, the front bumper of my car wouldn’t clear and I pushed the hose down the road 😯 the fire chief guy was not happy and a police man was upset as well because I was on a one way street with about 40 vehicles behind me.
Ended up getting the fire men to lift the hose whilst I drove under 😳
