Why do cars not have a standard layout for the controls.

My two cars have the indicator stalks and windshield wiper stalks the opposite way round. When I use the wifes car I usually wipe the windshield instead of signalling my intention to turn !!!!

Thankfully there does seem to be a standard layout to the foot controls !!!!

But I do understand your frustration.

Was looking at some RGB LEDS on a website today and the pinout was differnet for Common Anode and Common Cathode.
