Obviously not a resident of CA and doesn't spend much, if any, of his time riding between the lanes. (Lane sharing for TWN's benefit.) While Sacramento is just a little farming community and the need for L/S is limited, I have on occasion resorted to it and I "know" what JB means by, "leave-yourself-an-out". However, James, by using the 1st key, "Aim-high-in-steering" one can often anticipate problems far in advance and thus avoid having to use 3rd gear all day. Having viewed your "commute" which appears to be 80-90% "Lane Sharing". I think I understand. I still think you should use 5th, or at least 4th, more often....For the environment.
