Doc here,

On today's vehicles It IS a disaster..!!

Even on the most MODEST Vehicle today..If you reverse polarity, you will let the smoke out of :

The Alternator Diodes
The Regulator
The Dizzy Module (ECM)
The Computer
The CD/RADIO player
The Digital Clock
Any electronic Controls for Climate control..
The Instrument Cluster

Light bulbs aren't picky about what direction the power comes from, nor are things like flasher units, switches and the like..

But a DC motor with a reverse polarity SHOULD have turned backwards.. (Go figure?) ....

Imagine turning your heater on and watching all the stuff on the floor getting sucked up into it?

Years ago...hundreds of years ago..When I was in the Marine Corps, The Guys in the motor pool would Reverse push start them backwards in 5 th gear to get the engine to run Backwards (multi~fuels I guess weren't picky about which way they ran either)..and leave them Idling on the line..the poor driver would get in and discover he has 10 speeds backwards and one forward..
