AnnMarie is a scripter, not a builder. If you think they are ugly, send her a pretty one to use. A dinosaur would be great.
Her script is far from perfect but those that criticize have no idea what is involved. She is up to version 1839 after 4 years work and constantly improving it.
If they crash on your land, call her. She is very responsive and will diagnose the problem so it doesn't repeat. Just returning them removes the symptom, not the cause.
There is no script available to remove vehicles that get stuck on no-script land. Suggestions have been made to solve the problem but its unlikely the Lindens have someone to work on it.
AnnMarie says 25% of her vehicles have already been modified to morph automatically into boats or railroad cars as needed however the Lindens have stated they do not regulate appearance of builds, vehicles or otherwise.
Roadside land gets a premium price and the roads have abundant roadside advertising. Advertising is located there for visibility to traffic. 80,000 passengers of "unmanned" vehicles provide the majority of that traffic.
