Not quite any longer.
Older classic era cars used to have toughened / tempered windscreens, and side / rear glass.
Would break into thousands of relatively harmless (try telling that to your bare feet though !!) particles, not capable of cutting arteries etc.
Very hard to break though, like it can take multiple hammer blows, edges more susceptible to impact, but covered in a vehicle build of course.
Modern vehicles all have laminated glass, easier to break, but holds together if broken by impact.
Usually glancing impacts on cars, so seem relatively suited for this use, though star cracks from stones etc are a main issue.
Side and rear glasses are usually still toughened, but some euro models are moving to side laminated glass too.
Perspex (or more likely polycarbonate) in the heli windows (and many aircraft windows) are very strong in the curved shapes.
Almost impossible to break apart from a very strong hammer blow, or frozen chickens shot at it

UV light damages it more readily than glass though, so after some 10 years perhaps it could become a lot more likely to shatter / dull / craze.
