Yeah, stopping gets a bit ridiculous. Like, you can brake off the interstellar medium/destination star magnetically, or you could shoot a mirror ahead, and the focus the beam on that & bounce it around to brake, but it just gets really comical. Cars don't work without roads and regular interstellar travel doesn't work without municipal doom lasers.
How would they slow down the vehicle if there wasn't already an identical Dyson sphere at the destination? Sounds completely infeasible.
