~~For the occupants, any pedestrian hit by an EV will generally be in worse condition than if they were hit by an ICE vehicle.~~ ~~While this is ultimately good, the benefit can't be applied so broadly as "the breakthrough that makes EVs safer than ICE cars".~~ Edit: /u/inclementimmigrant had it right, not me The solution as always is to reduce car dependence.

wouldn’t the increased weight due the battery be partially compensated by a more lightweight motor? electric motors are significantly simpler and less heavy than ICE motors.

No, combustion engines don’t weigh much nowadays. 100-300 KG is common. Battery pack alone for a Model S is 544 KG, motor+inverter+transmission is another 140ish. For an RWD car, AWD of course adds another one of these (it also adds drivetrain complexity in an ICE vehicle, but not as much additional weight as in an EV). VW ID.3 is apparently 41% heavier than a similar sized Golf.
