For the history curious, here's some analysis on tank losses (Normandy):

Tl;DR: Initially most German losses were due to AP rounds (17pdr, 57mm) penetration, later almost half of German tanks were destroyed by their crews.
That makes sense... If your front lines have collapsed and your enemy is advancing 10-20 miles per day then what you want to do with any armored vehicle that has survived the first 6-7 weeks of conflict is GTFO. But if you have tanks with less-than-durable mechanical designs... and/or you do not have the logistical support to fuel them, then what you are likely to have to do is destroy them. After all, your fuel trucks and repair parts/crews have all gone BOOM when hit with 3" rockets, .50 cal rounds or 500 lb bombs.
That said, there were enough Panthers on the roads and fields of France that were abandoned or only temporarily disabled that the French were able to get almost 200 of them operational for a post war heavy armored brigade. It is from the long term operations of these Panthers that we know so much detail of their operational weaknesses. The French replaced them as soon as they could.
