Guys, have faith in our engineering skills. The cart is a completely self sufficient electrical and mechanical system that can stay active for a full day with the drive system being used and 2 days of just charging batteries (without needing a recharge). Every system has a redundant system to back it up in case of a failure. The system is charged by one AC input to a custom designed distribution box using relays to select shore power or inverter power. It has a descent speed and a relatively tight turning radius. It is very safe for the user as well as the surrounding people. For the driver it has a 4 point restraint system and for other people the cart has an emergency braking system that brings it to a stop within inches.

As for the magnetic shore power plug, that would be very unsafe, because when the magnet disconnects you now have a situation where the leads can be easily shorted, or shock someone.
