Wish I could go... I had the opportunity to attend the last Equestria LA convention in 2017. It was my first convention and unfortunately, probably my last.
I knew doing it for real on a busy street would be out of the question, so I thought of finding a road with nobody there and letting the car run by not holding the brakes. In the end I just decided to have the car in the parking lot with a stabilized camera and just cut out the outside to replace it by stock footage of a road. I had to use keying to extract the part behind my head, but otherwise everything else was cut out manually. I then created masks for the shadows so it would feel better integrated. After that I added some shake to make it feel like I put a camera there for real.
