Proteus- please stop armoralling your tires. lol thats bad for business.
In Ny the police write you a ticket that is a moving violation that is "traveling to fast for conditions" the police can issue that ticket without seeing you have an accident or even knowing your actual speed. If you crash in the evening and you tell him its because the sun was in your eyes he can write you a "driving with vision obscured"
If you have an accident or they witness you practicing these sideways stops. They can get you. basically if they want to . then they can. so just be safe.
I think the key is gradual breaking. You will get a feel for how much deceleration you can accomplish without breaking down your traction. You will learn how to modulate it.
