Safety is quite a relative subject. Old car doesn't mean it is totally unsafe. A neglected & lack of maintenance of new cars are even worst than a properly maintained, old junk.
Drive safely. TQ.
Quoted for the truth. In fact, the main thing that old cars cause on roads is slowing down traffic, either through breakdowns or the fact that since the car is old, the owner won't drive it fast, which may be a good thing in certain circumstances.
I see many modified cars running around on used Japanese tyres with less than 40% tread. These tyres are unreliable for we don't know their history or how long they have been on a ship before arriving here. Blowouts aren't uncommon.
Some supposedly "rich" ppl driving expensive cars with 18" or larger rims, sometimes end up using their tyres until there's no tread left. These cars are very dangerous too, especially in our unpredictable weather.
In summary, it's not wise to put a blanket statement and blame ppl driving old cars. If you are well off, good for you. But don't put down ppl who either drive an old car as a matter of choice or predicament. It's unwise, and highly immature.
There are no lousy cars. Only better cars.
