I would like to not share that I practically had all day yesterday to try but couldn't find my groove, but I regret to say I spent a lot of time trying. Too much. With no great runs.
This morning though, I had a couple good runs. I've been trying to create some resemblance of patterns in order to catch as many 3rd and 4th cars. One great find is on the 4th (I think) screen. If you get to the top section of the screen, in the middle, the cop cars won't come up to get you, giving you a small break and time to plan your approach. (I attached a pic below). Then, when the cop cars start 'bunching up' below you, you can bait them to come up on one side or the other, then make your break down the other side. If you are patient enough to do this several times - run back to the top, wait, and make additional runs - you can get though the screen and if you play it right you can get that 4th cop car every time. On your 'runs', either go for cash or go for cars. If you try for both, you'll be doomed. Oh...also, when the cop cars reappear on the screen, they come back in that middle section, so its best to have them follow you from the outside, then 'eat' them while running away from middle. Ugh, that's pretty wordy. Hope it makes sense.
Anyway, I got 83,030.
