Follow my drive web map should show alerts too
During Follow my Drive, your alerts and comments should be broadcasted too. Many times you're driving ahead of a group, and they want to know how the road conditions are. If your alerts appeared on the FMD web, they could see what you're reporting.
Maybe simply use the real time waze map instead of a blank map, so you can see alerts. Don't forget to include the feature for world.waze.com too and not just for the regular US waze.
