For cars and bikes alike, it all comes down to how much work the tires are doing, which is to say, how much hard acceleration and hard braking occurs, especially to the point of losing traction despite grippy conditions (burnout/skid), in conjunction with how much mass is being moved. E-bikes and e-scooters are going to be way worse than human power, per distance, because of the quicker acceleration/braking. My FWD scooter is always slipping on uphill climbs, but my RWD bike doesn't because the weight is shifted appropriately. Lots of considerations.
