does that suggest an experiment? Like adding mass and measuring time to a given d??

Yes it was definitely an experiment that we tried and we found that as we added mass to the car its momentum caused so much skidding that the accuracy was destroyed in exchange for less travel time. However after regionals and our first invitational (in 2 weeks) we will be doing more experiments with regard to adding mass.

Wondered about that. Sounds like that, along with mass, you'll get to look at the tradeoffs in wider wheels/tires which will reduce skidding, but potentially increase rolling friction. Have fun.

This may require a clarification, but I want an opinion first:

Let's say my vehicle's body is shaped like a capital letter "i" (like this), so that at the front and back end it is ~30cm wide, and near the middle, it is ~20cm wide. If I put my Measurement Point on the side of the vehicle, at the part where it is 20cm wide, is that legal based on rule 3.f.?

I don't see why that would be illegal, so I would say yes.

It's on the side of the chassis and between the wheels so I'd say yes

Thanks. The reason i asked was because on the event score sheet on soinc.org, it says something like "the measurement point is easily accessible to the event supervisor". So an ES might say that the point was not accessible.

Can they reach it? That note is to prevent teams from making event supervisors' lives difficult. As long as they can easily access the measuring point without moving the vehicle, you should be good.

Well, our vehicle will be pretty accurate, so they shouldn't have to measure anything anyways

An event supervisor at a recent invitational tried to dq me because my point is towards the center of my car, and although it is accessible, it is not on "either side" of the car. Was he right?

Can you say how far from the middle? As of now, my point is 6 cm from the outside of the vehicle, still 7 cm from the exact middle.

Pretty close to exactly in the middle, about 15cm from the outside of the vehicle.
