Wouldn't it be like driving through a tunnel? Granted it would be a bit weird that it moves (you can overtake it and vice-versa) but given it short length, you can easily focus on the road and compensate.

I think they might add a vanity panel so you can't see the tyres and trusses making hitting the thing less tangling and perhaps even add flashing warnings if you are veering too close to the thing. Given the width and height of the TEB it looks rather stable.
