It's not unreasonable to assume someone will have a line of sight for where a vehicle is being summoned from, just like when in the vehicle itself and you drive forward you're paying attention to its surroundings as well.
I have seen some videos released with summons that just a quick horn honk would have likely prevented another driver backing up their vehicle from bumping into, with enough force to do some front bumper damage, a Tesla being summoned in a parking lot; it moves slowly too, and that could also be a factor in surrounding drivers not gauging or having the same kinds of reactions.
