Personal definitions
Foot Brake : normal service brakes.
Emergency Brake: hand operated
Parking Brake :foot operated
A hand brake is easyer and safer to use to stop with during a brake failure. Back in 1999 Ihad a master cylinder fail on the off ramp @70mph, with a blocked intersection at the bottom. I tryed the parking brake it locked immediately, and the detent held it locked. Rear lockups are no fun @70. So drop into 2nd gear(auto)pop the park brake ,bending the lever over (prevent further problems trying ro modulate apply presure turning it into an emergency brake). Wile turning to correct for the slide. Long story short
No crash. t-case newly formed emergency brake and auto trans saved the day, I don't think I'd have been as lucky with a manual trans 4pedles ,3 in use 2 simultaneously modulating more than my ankles can move.

It seems crazy that automatic transmission cars have hill hold feature, or that people would care about that.

Its a manual feacher.
My 06 Subaru Forrester XT (big body WRX) had it loved it till i was going down hill on a dirt road ~30-50° slope 1st and rideing the brakes was too fast , hit the cluch and lost the ability to modulate brake presure causing a 4wheel slide @ .25 mph had to release the clutch to release the foot brake. As with all things there aer +and -.

Flat tow /drive wheel down
All depends if there is spmething on the output shaft to move lube. Some manuals are not safe , almost all autos are not if in question call U-Haul. We had a book for hook up compatibility tell them you are planning on towing behund an RV . Many rigs have kits that add a pump to the trans or disconnect the driveline/shaft.
The big push for police to abandon Chrysler vehicles was burning out the transmission following a persuit. Cause -no or low fluid cooling in Park the transmission needed to be in Neutral or a drive gear to activate the pump for cooling.
