That makes his lead 3miles in front of you. But, you accelerate to 290, and with your 40kt overtake will catch up to him in 4.5 minutes. That will take you another 22 miles to catch up to him.

Bottom line...You're going to have to travel over 30 miles, and say 8-9 minutes(+/-) just to have any possibility of a collision. Doesn't seem real scary to me.

Having said all that...I think it might depend on if I'm trying to catch a D/H home on the other end.
