True, but modern car manufacturers manage it. If, like me, you have spent time working on cars, you will notice that nowadays, electrical connectors in the engine bay and suspension components are quite securely sealed against water ingress, with rubber or nitrile O ring seals*.
Considering the price of an ACP or RMP, (aircraft communication boxes), it would not seem too much to ask for a similar level of protection against liquids. It is harder though, to seal a shaft that needs to turn, such as a volume control, and Comm boxes have lots of volume controls !

Yep, TCX had this rule. We still went bust though..................
