You can find soo many more openings in traffic,

Please, please, please don't do that. Cars are dangerous things and when traffic is so close that you're looking for openings, it is too congested to get in there. Safety should be your first priority and that means you're looking for openings that even a car with a tiny little one liter engine it has more than enough space to get in. If there isn't a big gap, just sit back and wait for one, It's a sign that your city needs more roads. Not a little more roads like the people say one more lane, a lot more lanes. Generally by the time people are asking for one more lane, they need five times as many lanes. Yes, that's expensive, maybe you should look into public transit instead.

Great safely folks. I've lost enough friends to drivers who were in a hurry. Please don't add another one to that list.
