OK, let me play the other side for a moment. (yes this is what I do)
You put the cops there to do a job. Most are taught "spirit of the law" vs "letter of the law". How you are treated in this most of the time is up to you. Do you give the cop a bad time because "your not hurting anyone"
What is the diff between you and an 8 year old on a minibike? You are older and know better, the 8 year does not normally.
Do you have legal lighting on the cart? DOT tires? Do you follow the rules of the road while on the cart?
Remember, most cops are good guys and will tell you just get it off the road. That is what I do 90% of time.
Traffic cops are a diff and need to keep up with "performance requirements" (quotas) and will cut you little slack.
Yes, I ride my cart on the street, but not alot!!!
