This is an honest accident, there is no intention that I want to
challenge you kind of stuff, sometime, accident like giving way or
both gia gia dun let go and purposely go knock each other and see
who more beng, then that is more on egoism accident.
I will take it as a pinch of salt, but some old man are lau gui,
very rich hor, of course kena hit sure act poor lah, if I am the
old man, I said, $300, if not my workshop, I paid for the repair
and give you $100 for your time…lai lai sin ming..
let's say u wana cow tim the repair cost at ur own wrkshop n
just pay $100,I think not enough
let's do a simple breakdown
drive down to ur wrkshop,after tat need to take a cab hm,wen cab
is ready need to take another cab bk to wrkshop
up down travel cost aga aga $50 depend on where u stay
cab rental for one day $100 (depends on wat model)
lost of income $200 (driver's choice)
total amount without counting repair cost = $350
if wana add repair cost should be more,another prob is if the
driver is a relief n not omo how ah? need to compensate the lost of
income for the hirer too? suck dry dry lol lucky hammer is omo
that's why I say hammer is a kind hearted person
he could hv makan more but he didn't 
but end of the day it's better to settle pte if damage not
serious rather than go report n lose 2k n add one accident under ur
record
