If you simply change everyone's temporal frame of reference by the exact same amount, you have done nothing, really. Everyone will simply account for the 500ms delay, and trades will still execute in the same order.
Exactly. So look up IEX. Their solution is to 'position' themselves electronically to be *EXACTLY the same number of ms away from all the major exchanges in the U.S. So when they execute trades across 5 exchanges they all happen at EXACTLY the same time on all the exchanges. Thus those HFT guys react too late, all the needed buys for the specific transaction have already occurred. HFT Guys loose. Bummer.
It's not all about speed it's about timing.
That said around here you would be one of the 10% that know what a signal is for. If I see the vehicle behind me with a signal on and I can make way for it to turn I will always accommodate that if it means moving up, moving over a bit or even speeding up on occasion. I will NOT do that if the vehicle is flashing it's lights, sounding it's horn or tail-gaiting.
Additionally 90% of my driving is two lane rural roads where slip lanes simply don't exist and stop signs are the norm. If I roll up to the car ahead of me as it rolls away taking it's place at the stop sign I have perfectly executed that intersection. Even if there are 50 cars behind me I am hurting exactly nobody.
I also think you need better brakes! My vehicle has 145,000 miles and is 8 years old and still has the factory brakes, inspected just last month. 6 months? Really???
Oh and I don't think I've printed more than 1 email a month for the last 5 years anyway...."
AND most of these units can take the heat pulled from the house in the summer and put it into a hot water tank for DHW use. Really and truly $FREE hot water.
