don,change is good,if properly implemented with a touch of common practical knowledge,but we live in sri lanka(don't get me wrong,I love this country),where cops don't know anything about cars,do you think they will understand difference between various kinds of seat belts?do you think they will understand the difference between a kitted civic and a low riding ferrari?
ahhh if it was only easy as you say...few people understand the complications of adding a accessory to a car which is behind it's time,and still keep the car original as possible,which is the whole point of owning a classic.I'm sure most classic car owners will wince at the possibility of a scratch on the body let alone drilling a hole on their baby,bear in mind that not all cars have side verticle pillars...
I'm all for seat belt safety,they do save lives,but your point of saying "hey let's force this on the classics as well" as if they were a major threat to road safety without proper knowledge or expierience is not right...
Thankfully the government hasn't implemented this rule to cars that come without seat belts so I can rest easy
