Vehicle rules?

I've been tinkering with advancing the Dragonmech setting a few decades game-time, enough to produce some serious changes.

One of the things I'd like to do is simplify the mechs.

Someone on another forum made some rules for vehicles which look interesting enough to use.

The basics is that a vehicle is an animated construct that you control.

So, vehicles are handled like this: they are essentially animated objects that you control. Their type is Construct, and if they do not move they are flat-footed. If they do move, they treat their Dex bonus as +1 per ten feet moved in that round - so if a vehicle speeds 250 feet up to you, it seriously has +25 AC.

I may use the basic idea, and a few others, to make a basic mech creation system.

I like the idea of simplified mech combat. I have plans for a big multi-mech showdown in my game, and in the absence of dmech battles, I'm curious to see how it works out.

It basically comes down to "You don't need crew, just pilots and gunners."

The stat block would be simplified, and you could use the maneuverability and a pilot check...Which, I see I forget to include that variant...
Pilot (Dex):

Normally, piloting a vehicle in regular conditions requires no roll if you have even a single rank in Pilot. If you don't, you'd be lucky to get it moving in the first place, and then it's a DC 10 check per minute (otherwise it stalls or spins out or whatever).

If a vehicle has the hatch open and is hit by an area effect ability, a DC 15 Pilot check is required to prevent the crew from being affected (not an action).

Pilot checks to keep control of a vehicle in difficult situations:

Make a DC 10 check, with modifiers for all of the following that apply:

Difficult Terrain: +3
Dangerous Terrain: +5
Sudden Turns: +2
Concealment: +10
Full Concealment/Blind: +20 (does not stack with Concealment)
Vehicle is taking Continuing Damage: +Damage
Hit by Ordinance Weapons: +10 (Vehicle-Mounted-Only Heavy)
So, yeah, you could make do with a maneuverability score and those modifiers.

And the creation and critical hit rules could be simplified down. The creation, I think, would be the biggest undertaking, because I'd be using some abtracted rules for money and creation time and all that. But for everyday purposes, it could be handled by having several mech types and those could be copied. After all, if a gear arrangement works for one mech, it'll work for another.
