I've modified mine as I've gotten more comfortable in traffic. I changed mine a little bit this morning. I usually cut through neighborhoods with stop signs every couple of streets, you can imagine how annoying that is. Today I said F it and took a larger street with 0 stop signs. I covered that part of my trip alot faster and was not as tired. The other thing is a had been worried about traffic and didn't take that street, I'm kicking myself because I took it today and I was the only one on the road. I could have been taking it all along.
