I have stopped trying with my new CF bike. A nice old steel bike is great for lights. I also used to tip my bike over to get pedals and BB as close to the pavement over the line as possible. I am sure people wondered what the heck I was doing, but there are certain lights that it would work, but you need to know the phasing a little so you can be ready to go when the light turns green. Hopefully soon more lights will be switching to camera activated lights. They are much better at picking up cyclist and can possible eliminate cost down the road, since you don't need to replace them every time you pave. Unfortunately, most DOTs only have enough money to care about this year so they don't spend money to reduce the cost in the future.
