A pusher trailer works well with an electric car because you can use regen braking to slow the trailer down and from your electric car more or less drive just throttle the trailer.
If you tried to use a pusher trailer behind a gasoline car I think you would spend alot of time ridding the brakes and trying to run two throttles because the pusher would be moving it's own weight, the weight of the cargo and the weight of the lead vehicle.
The idea of an electric self powered trailer is that you can have the throttle as part of a telescopic hitch and instead of needing a hand throttle inside the vehicle allowing you to focus on driving and making sure that your load is staying secure, also with electronic throttles you can program in the lag time that would take away any jerky-ness and going down hills or coming to a stop would kick in regen braking.
Also an electric trailer would cut your gasoline use, allowing a 50mpg car to still get 50mpg while hauling a ton of dirt.
