It's also the best place to be to maximize damage if you happen to rear ended. It's also illegal where I live (edit: for specifically e-bikes).
Also, riding where cars/trucks/whatever mirrors are able to see you is another dimension.
Also you can see much farther between cars.
I usually ride switching left of the lane to right of the lane occasionally, to create lateral movement so car drivers will notice more (one hopes).
