What are some techniques to get a shot of the driver of a vehicle, while driving, from the front passenger seat? In the past, I have seen camera operators sitting in the front seat, camera on their shoulder, facing backwards. It's a great 3/4 shot and avoids anything too profile-y, but it's not safe by any means. No seatbelt, back against the passenger airbag, I hate to even think about what would happen if there was a collision of sorts while shooting.
So, what are suggestions for achieving such a shot and keeping everyone safe?
