Did you know?
You can test all the vehicles I've made at the shop: go through the door at the left labeled "Runway".
You will see all the rezzers for all the vehicles I've made, you can fly, or ride them all, but here's a catch: if you manage to smack your test vehicle against a sim border it will disappear and you'll probably end underwater lol.
So test your skills flying under bridges or try to ride a pennyfarther on unpaved terrain and have fun!
