They get disabled for 5 minutes, probably to give the motors time to cool down.

If the motors need to cool down, they need to rethink their motors.

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. So do motor controllers, MOSFETs, etc.

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.

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

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.

Rethink a motor designed to be used for 5 mins initially then occasionally in future? It's fine for the design purpose. It's even fine for the mode where it operates every time you get in the car (where it waits in fully back position, and moves forward when you operate a control)

Why should they think it to let it be used as a fidget toy?

Phew, that makes a lot more sense. I thought it permanently locked them
