These "low clearance" robots hang out a considerable distance as they traverse the bump. This brings up several questions:
1. If a "low clearance" bot goes over the bump and comes down on top of another bot on the other side of the bump, is there a penalty? <G38>
2. If a "low clearance" bot is extended (hanging out over the edge) of the bump and another bot comes up underneath it moving in the opposite direction, it is likely that the "low clearance" bot will be flipped. Is this a penalty? <G36>
3. Does the answer to either question change based on "intention"? (How will a ref know?)
4. Is the bump a true "anything goes" zone?
From what I understand - a "low clearance" robot runs a substantial risk of driving on top of another robot, which violates <G38b> - so they've got to be real careful going over a "defended" bump.
On the other hand, they run the risk of being flipped by an aggressive defender, possibly making a defender guilty of violating <G36> which would suggest that blocking a "low clearance" bot is a very dangerous strategy.
Humm...

The following is my opinion and not that of a FIRST referee:
1> Maybe
2> Maybe
3> Not so much intention, but how flagrent it is
4> Most likely it will be the wild west. Expect contact, expect contact outside the bumperzone, and expect to get rolled if you are not careful about where and when you cross.

When an 8 wheel drive come over the bump trying to get into the zone you are defending, do you:
1. Get to the top of the bump first and deny them that position,
2. climb the bump at the same time as your opponents and hope to make bumper and bumper contact only,
3. push them while half their base is sticking out at the top of the bump,
4. Sit on the incline on the your side of the bump such that when their robot cross over, they will land on your robot,
5. wait until their robot stabilize on top of the bump before climbing and pushing,
6. or wait for your opponent to cross the peak and begin climbing down on your side before you start pushing.
I can see option 3 is being closed to violating G36, but option 4 might be acceptable to people.
Bear in mind all of these will happen within a split second, making it hard to tell what actually happened. What's the difference between climbing up your side of the bump, getting your front 2 wheels at the top, sit there, versus climbing up your side of the bump, get your front 2 wheels at the top, and begin pushing when the other robot gets there?

Again my opinions here:
1> will get the defending bot rolled
2> Best scenario, and the least likely to happen in the heat of competition
3> Most likely defense and most likely to roll the crossing robot
4> Least likely to happen because it'll be the most likely to damage the defending bot
5> Won't happen
6> Give up the advantage? won't happen.
Considering the options, anyone building to cross the bumps should be prepared to have to right themselves or figure out how to cross and avoid defense.
I know this isn't what you wanted to hear, but I suggest you design for 'vigorous interaction' with other robots.
