You would have to drive faster than the speed of sound in order for water droplets to cause your windshield to shatter. XKCD FTW.
Fortunately cars can't do that. My neighbor ticks me off enough when he goes flying down our street over the speed bumps at 2 AM.
I don't think a car can go that fast, jet airplanes fly through the rain at 500 - 600 mph without worry.
iv done 120-130 in rain before, on the pkwy no problem, you should be more worried about tires, traction, grip, and suspension then your windshield lol
Frozen rain maybe, any other forget it you won't be driving.
You Will have to go about 560 miles per hours so you can go faster than the speed of sound that will cause raindrops which fall at about 75 miles per hours to be able to breal your windshields
How fast is it?
