Center line bonus

As per the rules, Center Line Bonus is given if the center tape remains completely within the vehicle's widest wheelbase.
The term "Wheelbase" means distance between front and rear wheel.
https://en.wikipedia.org/wiki/Wheelbase
Does it means that both front and rear wheel needs to be within the center tape ?

Not sure whether the rule used the wrong term "Wheelbase". I feel it should be "Track"
The term "Track" means distance between wheel in an axle.
"Widest Track" makes more sense than "widest wheelbase"

Do I interpret wrong here ? Can anyone explain please ? I tried to clarify with SO, but not got response for a month.

Re: Center line bonus

Yes, you've interpreted it wrong.
The "wheel base" is the distance between the left and right wheel.
So basically the left or right wheel can't stray so that the wheel goes onto the center line tape or farther.

Re: Center line bonus

can you please check on the below links. Wheel base is defined as distance between front and rear wheel/axle

Regardless of interpretation, what Wikipedia calls the Track is what was intended, since the other interpretation is (as you noted) impossible. I haven't looked at the relevant section for Battery Buggy in particular (basing this off of previous vehicle events knowledge), so I might have missed something.

Re: Center line bonus

If you're basing the rules off of wikipedia, then ur saying that you need to face the car perpendicular to the center line and make the wheels move toward the center line (so the car moves literally to the right or left).

Yeah, I don't think so.

Re: Center line bonus

I do not see it clarified anywhere. For example what if most the wheel is on the centerline and part of the wheel straddles it? Is this good? Or does the whole centerline tape need to be fully between the wheels.

I have dual wheels on one axle. Even more questions arise lol

Re: Center line bonus

From the judge’s perspective it would be really tricky to see if the wheels touch the tape underneath a quickly moving vehicle - I think contact with the tape would still permit a bonus. The judge can only see the floor clearly outside of the vehicle’s width. If the judge sees any center tape to the left of the left (or left-most, in the case of more than 2) wheel, or to the right of the right wheel, no bonus. I’m wondering if supervisors at high-stakes competitions would record video of runs to review a close call.

Re: Center line bonus

I think that makes sense (like to take a video of each run)

Re: Center line bonus

Since the centerline bosus also states 'between starting line and target point' would it be true that a vehicle that is 1 cm short of target but straight as an arrow would not receive bonus?

I don't think so. 7.e has the phrase "while the vehicle travels" - so if it stops short of the target, it's stopped traveling, and the bonus would be applied based on the run. The purpose of the "between starting line and target point" is to emphasize that the bonus still applies if it veers off-center, beyond the target point.

Re: Center line bonus

So it's to your advantage to have 30cm wheels in the front or back, or both, which is the maximum width, to ensure the center tape is completely within them.
