Yes the wireless charging pads are insufficiently bolstered for hard driving.
I sent my phone flying off once or twice in my M3P, though more from cornering than acceleration. Now I put my phone in the cupholders or other more secure location for really hard driving.
Mostly I just don't push the car quite that hard anymore after exploring its limits early on. Also I have a bigger, heavier phone now that stays put better (went from Pixel 3 to Pixel 6), well enough for twisty roads where there's no room for getting too aggressive.
