Second out of town drive

With the cooling system installed we decided to chance a road trip.  Successful 48.4 miles.
Lessons learned:

1. Regen ON causes far more heat build up than with Regen turned off.  Regen is when the energy from slowing the car down is reabsorbed through the motor and placed back in the battery system for reuse.
2. The accelerator pedal is setup such that the first 1/4 of the pedal travel is Regen, and then Acceleration.  There is enough regen capability that the actual brake system does not need to be used in regular driving.   FYI, the Regen system activation does cause the brake lights to turn on.
3. We need more cooling; it is not clear yet whether the pump is not pumping, if there is a blockage in the lines, if the system has an air bubble, if we need the fan on the radiator blowing, or if we just need a larger pump.  Regen is off until we figure this out.

UPDATE:

The cooling system is completely functional, there was an air bubble caught in the system.   Excessive regen use does heat up the motor core more than the motor housing, but the system has not auto de-rated since install of the cooling system.
