Correct.
I'm curious, what could happen if the car was running?

The alternator in the car generates a *lot* of amps continuously - around 70-120 average at around 14.4 volts. This power goes somewhere, and it could drive quite a lot of current through your bike's battery (and other electrical components) and fry them.

Your battery might go bang :D!
Of course I'm generalizing from a single example here, but everyone does that. At least I do.

Just make sure the car is same voltage. Most cars (American) were 12V in the mid to late 50s. (VW in 68) Some Honda (bikes) were still 6V at least as late as 86. HD went to 12V in 65 on most bikes but some of the Aermacchi (Aeronautica Macchi) built ones kept 6V a little longer. Also be careful of earth on car and bike. (some Europeans, especially the UK, may use positive Earth or ground) I usually leave car running, but my BMW and Harley both have bigger battery (larger and more CCA) than my Nissan.
