So… this just happened. Was corralling bunch of zeds into one dense group using the motorcycle. Grappler zed managed to pull me from the seat but I ended up at the tile that was adjacent to the seat. Instead of panicking, I just pressed ‘->’, and voila, I was riding my vehicle again (it was still going 34km/h). The action itself spent couple of turns where I was unable to do anything but then one press of ^, and I’m controlling my 'cycle again. Is it intended behavior? Because while I did it hoping it’d work as it did I wouldn’t be surprised if instead my motorcycle would run over me instead.
maybe not intended perse, but is not a bug, i think it is able to happen since the vehicle speed affects the “move points” you have per turn, that why if you are lucky enough, you can re ride it again
