Getting into an accident, even a minor one, gives you a lot of inconvenience and repairs are expensive. Even if you don't have to pay, it may affect your insurance premium. So drive with care.
I had a small unfortunate accident not long ago. The damages are shown below. Inside, one top corner of the radiator was dislodged from the front of the car but the car could still be driven normally. How much you think repairs cost?
OK, give you answers to choose, to the nearest $100: $800, $1200, $1600, $2000
Fortunately, I had an eye-witness and I think the other side was honest when making his report. But still there was the hassle of taking down particulars & taking photos, reporting, sending to workshop, looking for witness to get his statement, etc, etc.
The workshop claim advisor told me that if the other party admits that it is his fault, get him to write it down and sign it on the spot, lest he changes his mind and blames you later on.
