Doesn't mean just open door and kena hit means you in the wrong.
All depends on circumstances. A taxi (or any other car) has stopped
by the side of the road, hazard falshing, no obvious danger to
other road users, driver alights to retrieve or do something, then
out of now where a car comes and hits the door.
Is the 1st driver in the wrong? the Law never states you can't
stop on the side of the road and alight except along zig zag
lines.
So all depends on the circumstances. TS or his dad should know
best and decide if he is in the wrong or right. If right no need to
worry, report. But as Td, must consider the cost, loss of deposit
(another 1k until case is resolved). $800 might not too bad a
figure considering it's a BMW if the TS's dad is in the wrong.
