Motors get hot and it’s quite reasonable to not include tons of cooling just so that you can adjust your seat for hours on end.
That said the implementation is still stupid as time isn’t the right measure to judge motor temperature, motor temperature is. Thermocouples cost fractions of a cent, the motors probably already include one or two as they already have smarts (being hooked up to the CAN bus and not straight voltage). Which would also take care of differing environmental temperatures as obviously the motors are worse at shedding heat when it’s scorching hot in the car.
Potatoe Potatoh. Point is you size the overall system for quick adjustments, not continuous use. If you can get by with less weight and cost then you do as continuous use does not even begin to appear in the requirements sheet.

You don’t add cooling, you size the motors to have enough thermal mass and mount them to metal chassis.
