We have white stripes painted across the I-10, I-95 in areas of rural stretches, 1 mile apart. The Bear-in-the-air times you from 1 to the other and relays your time to the ground cars that get you...........
Here in Cal-E-Forn-E-Ahhhh-—Huh? we have tick marks painted on the shoulder off the fog line....maybe a tenth of a mile apart...or an eighth....or maybe a quarter...I’ll have to check....but not across all lanes...just from the fog line across the shoulder.
