Not necessary. Small chips are not that detrimental, unless you
regularly travel at breakneck speeds on NSHW. Even that does not
mean your windscreen will automatically fail.
If the windscreen is covered by solar film, I'd leave it alone -
unless replacement is FOC. In the unlikely event of failure, I can
always pull over safely and have the car towed to w/shop.
However, if there are tiny crack lines at the base of the chip,
I'll replace it ASAP, because a failure is imminent. Better to take
your time to hunt for a cheap workshop than being carrot-headed by
another workshop when you need emergency replacement.
