Fact of life here in MA as well, much worse when it's hot out and the patch tar softens. \\; Corners are definitely dangerous, and I've even had the rear tire slip once when passing a car and under heavy throttle.....scared the sh*t out of me.
Tar strips are an accident waiting to happen. \\; Hot or wet I've come close to going down if I hit them. \\; If you can't miss them slow down and hit them as square as possible. \\; The straighter the bike the safer you will be. \\; And the WADOT don't care about them and bike safety around here!!!
