Quiet honestly, you are never using as much of your tire or your bikes potential on the street as you think you are. Even if it feels like you are "THIS CLOSE" to getting that knee down or the bike leaned all the way, you arent.

Since you cant get the necessary conditions on the street that would enable you to "safely" (used loosely) push the limits, save it for the track. Enjoy your weekend rides, ride within your limits and a bit below, especially if you have a fear of crashing, and I promise that while you may not feel like your skills are improving, they are and the more you ride, the better you get, without even realizing it.
