So one thing im finding extremely frustrating with vehicles such as any walker or repulsor unit, is when you move the unit close to a building on an angle.
What happens next is this.

Because you move along the tool and treating the building as impassable (same for a T47 if the building is bigger than height 2), it cant be done, no matter which tool you use and how you bend it. The only thing you can do to get out of this jam is to pivot or reverse.
What i suggest is a vehicle action that allows you to Side Step (walker) or Barrel Roll (repulsors, like Xwing). Yeah it has the same action economy as pivoting or reversing, but allowing a small side step options up movement options and even firing solutions. Sometimes a target becomes presentable with a simple shuffle to the side, but right now it takes 2 actions to get out of the above jam.
You can argue that the vehicle shouldnt have moved there, but sometimes its unavoidable especially those with a compulsory move on a map full of impassable terrain.
Thoughts?
