Ugh, unfortunately I saw one this year on the BP MS150 (Houston to Austin). They provide an alternate route, but one Jeep was around every day. They have a TON of support, plenty of sag vehicles and a lot of motorcycle medics/sag. With 13,000 riders personal sags are just a bad idea. The Jeep driver kept slowing for her rider, following along. She would have been hindering traffic at anytime. It isn't fair for one person to witness their rider and it would not be safe for everyone to bring along fans. That is what the grand finish of the MS150 is for! Annoyed the snot of me.
