It's my impression in an entirely subjective way that cars are slightly better behaved if I have a daylight running "death power road drying laser" generator front light on during the day. I think they think I am a motorbike
Had that with an "Aquacars" driver in Porstsmouth
At the time I was running a Hope 3 LED light ( about 350 Lumens)
Approaching a junction, when "Aquacars" finest pulled out in front of me.
Braked to a stop about 18" from his door, with him now fully lit up along with the car
Me: Could you not see me, the lights are bright enough surely?
Aquacars: I bought you were a motorbike!
Me: So you saw me and thought I was a motorbike, but stilled pulled out?
Aquacars: Motorcycles have better brakes, and would have stopped quicker!
Me: So what you are saying is that whatever vehicle was coming along, you were going to pull out in front of them and force them to brake urgently?
Aquacars: Not my problem if you found it difficult to stop in time!
My only regret was that this was before I invested in a helmet cam!
