Movement is problematic, but honestly, the heart of the problem is the Speed table. It makes no freakin' sense. If you changed a vehicle's speed back to a flat movement rate, like it was in 4th, the Movement power wouldn't be nearly as ridiculous.
Going by the Speed table (page 202), the following vehicles aren't even legal to take on the highway, because their top speed is below 30 mph. (Speed 3)
Dodge Scoot, Yamaha Growler (on road; it apparently goes 60 mph off road), C-N Jackrabbit, Ford Americar, GMC Bulldog, Ares Roadmaster.
But wait, that's just ground vehicles in the core. Stolen Souls had some too. Let's add those to the list.
Chrysler-Nissan Journey, Espirit Ind. Watcher, GMC Sidewinder, Honda Artemis.
Stolen Souls even has vehicles lower than Speed 3 though.
Speed 2: Conestoga Trailblazer, S-K LT-21. Top speed of 14 mph.
Speed 1: Trailblazer with trailer, Dodge Ram Industrial (large and narrow). Top speed of 7 mph. An Agility 6 character can WALK faster than this.
Speed 1 is truly the most absurd. Walk rate of 5 meters, Run rate of 10 meters. The average human, Agility 3, is faster than it. Walks at 6, runs at 12.
