I am wondering for my specific situation, if I need to zig-zag or if it's just wasted effort.
I do not have a garage. I start my bike and let it warm-up while I put my gear on. 9 times out of 10 I am jumping on the freeway to get where I am going. They freeway entrance is just a few blocks from my condo, so I do a quick couple zig-zaps before taking the freeway entrance, which is one of the sweeping circles.
Thoughts?
