Mr Mayor, 15mph is dangerous - 25 would keep up with traffic instead of impede.. ALSO, there are warnings posted on machines by manufacturers against more than 1 occupant, Helmet requirements, underage (16) operators, and roadway operation..Easy.. I always thought that parents who bought these $6,000. toys as babysitters for their kids called the kids "spare parts" as organ donors.. People who have for whatever reason lost their right to  drive need to buy roller-skates, that should be funny when they're plastered..
