When I was writing the script, I had seen that at CES 2020, they were testing out driverless cars, and I thought that it would be a nice gag to have the trio think they would get some kind of lead by apprehending the driver, only to find out it's what's essentially a driverless Uber vehicle.
Hopefully there haven't been other shows/comics/etc. that already beat me to the punch, by the time we were able to draw this page. ^^;
