You do not understand thermal shock. Remove your windshield and bring it inside. Lower your thermostat to 63° and let your windshield equalize at that temperature overnight. When the outside temperature reaches 90° the next day, rush your windshield outside.
Conversely, wait until winter and your windshield is left overnight in 35° temperatures. Boil a large pot of water, and dump the boiling water on your windshield.
It is not at all surprising that for 150K miles, your car's windshield has never experienced thermal shock.
