Hm, let me calculate that
8 scooters cost 41200
Roadmaster 52.000¥ Speed 3, so only gets up to 20m/turn but has a Body of 18
Ramplate costs 250¥*Body, so 4500¥
At ram speed it will do 36P AP-6 + net hits
and receive 9P +1/4 net hits AP-6 in return.
It does have Bod+Armor 36, 30 after AP and can buy 7 soak hits.
Considering that it only takes 9 damage for it's handling to fall to zero, I wouldn't count on this a my default mode of attack (although it certainly is very impressive damage, albeit only in places where the roadmaster can fit in)
@fserpent
Do you refer to the Ferret RPD-1X Wheeled Perimeter Drone? Those are more expensive than the scooters and have worse speed. Also drones would have problems wielding the troll sized lances as they need bigger and more expensive weapon mounts.
