Don't know if I'm making this up after the fact, but horizontal electric screws into holes in vertical pegs or pins.

So, this bucket of crap has run 24 hours of LeMons repeatedly. It is a Dodge Omni GT rebuilt by Jet Electra as an EV back in the day of gas lines at the pump:

Yes. None of the usual limits.

That is a smart solution, hey. Here is what jalopnik said about a plausible EV LeMons prize build: https://jalopnik.com/lemons-is-doing...-le-1843973755

Get a base car that is cheap, something relatively lightweight and sporty with plenty of aftermarket support and knowhow, like perhaps a Toyota Celica or an early 1990s Honda Civic. Grab the CVT and integral electric motor from a XW20 Toyota Prius from the junkyard for a bill or two. That motor is good for 67 horsepower and 295 lb-ft of torque, which is plenty for a winning Lemons car. Build at least three swappable racks of LiPo batteries generally used for RC planes and the like. Build a swapping mechanism that allows these racks to slide into the car like cartridges and facilitate a sub-30 second refill.
You ramp might be the way to something like a 30 second swap.

Not sure about "TOY" lipo packs since I have failed them in spectacular ways. Should be able to hot swap under 14 seconds if held internal.

Why not a tesla drivetrain?

That's the thing, the EV had to cheat. You get $500 to spend total on the vehicle. If all $500 went into batteries, you might get a 4 kWh pack.

The only explanation I can see is that the rules allow an unlimited amount of money to be spent on safety including the fuel cell. Perhaps they regard the battery as a fuel storage cell, and therefore exempt from the $500 limit.
