Totally agree. There will be very few times when you will be able to use them. But at the end of the day when the main pack has thinned out, you should be able to use them. Just be careful and stay to the left of the right lane. Depending on how long the day is, and how early you left, there may only be a handful of riders around you at any given time. Having said that, do not use them early in the morning. Also, obviously, get off of them while entering towns. No matter how thin the pack is, it gets heavier near towns.
