My brother hab an accident with that situation. The other Driver overtook a bycycle and
my brother had to drive off the road to avoid a head on colision. After 2 years in court and
after three hearings the other Driver finally confessed that he overtook the cycler.
At first he said that there was no cycler, complete liar. But the cycler just took of and my brother had
no witnesses. In the end my brother got his Money from the insurance, but had to wait 2 years.
Without his legal expenses insurance that would not be posible.
With a daschcam, the whole hearing would have been 5 minutes and done. But they are also not allowed
here in Austria. I drove for a couple years with a dashcam until i got fined for it. Since then i only ride
my bike with a helmet cam, no more dashcam in the car. But i also have a good legal expenses insurance.
Just in case.
