Cars see radically different temperatures. Park a car in Phoenix for 8 hours in the sun, or let it sit overnight in Anchorage. My iPhone can’t be left on the dash in sunny weather without overheating. Even in the Bay Area, commuting home with Waze forced me to mount it on an AC blower with the case off.

A car screen will take hundreds of thousands of kilometers worth of vibration over the expected decade+ of use, lots of direct sunlight exposure, wildly varying humidity, temperatures of anywhere between -35C and +80C and it will work just the same. What you're describing is nothing compared to that.
