Easy Vehicle Test on PTR?

[zork]

Does anyone know an easy accessible vehicle test for a newly generated lvl 90 char on the PTR?

Need to test some vehicle stuff.

Not to familiar with ptr, but if you have access to old instances..

Ulduar?

Or maybe that Trial of the Champion instance where you're mounted with spears.. maybe they're not considered vehicles? :P

The Argent Tournament jousting mounts are considered vehicles, and you can pick up the first "learn to use the mount" quest without any prerequisites if I remember correctly.
