Thx Jason! That's some good news!
Under "TEST NOTES No2" they (R&T) write:
"Initial brake bite relatively slow - might explain fairly average braking distance." IMO that means there's some EV regeneration interference with braking. Narrow tires and mass alone can't explain such high braking distances especially knowing there's issues with initial brake bite. Initial bite usually occurs at relatively high speed when brake power and in this case a good EV regeneration/brakes integration management are more important than tire/surface friction.
