If u are unlucky, shit happen anyway, so even if u drive the
best bullet proof car and suddenly the tree fall on ur car, u still
die!!! A car can only protect u so much. Dun forget drunk driver
driving big vehicles (truck and lorries) will still kill the driver
in the world most expensive car too. Unless u drive a tank, then
dun compare incident that are beyond ur control lah. If u want to
compare, comment on the car performance or crash test stuff
lah...
But for a car that is cheap and dun go fast, if the driver are not
reckless, it should be ok. But there other issues that need to be
consider when buying thing that is cheap. Such as, is the car is
reliable, prone to break down, poor driving performance, etc?, Is
it likely to cause accident due to a sudden malfunction as a result
of poor made? I think those are more valid worries rather then
other cars crashing into u.
