Because you are a normal functioning member of society. Hell, I haven't even wrote a ticket in about a year. Normally it is a "slow it down, be safe, have a nice day". Unless you refuse to provide a drivers license. Then you go to jail. If you still refuse to provide any type of personal information, you might be detained for homeland security to verify your citizenship. And they aren't quick.
It's apparent you don't operate on Redstone Arsenal ($80 ticket for 30 in a 25) or Atlanta ($185 for cutting through the hashed out area between the on ramp and the interstate) or Auburn in the late '90's ($90 for 55 in a 45) or in Grove Hill, AL in the early '90's (76 in a 55, Don't remember how much that one was, I just know that I got grounded for a good long time. Luckily I did know the DA, got to go to driving school so this 16 year old's insurance didn't triple).
