No, no personal experience
I now pretty much drive like the old man i'm becoming. I have too much on the line at this point in my life to lose my license (and then my business and then my house, etc). Guess i'm becoming my dad.
However, the new laws have been quite the topic on another local DFW board where the members are younger and some do participate..... on unlighted tracks with no timing equipment in the country.
All i'm saying is that getting caught now carries a huge whallop that wasn't there before. Having your car towed and your license suspended for a year is no joke. Be careful.
