I've been keeping a nice distance from others on the highway and keeping cruising speeds under 65 mph
no bra or anything.... has been working very well
if i rip the car and drive the way the Z it's supposed to be driven.... i make sure theres no one around and theres no traffic up ahead.
in normal-to-heavy traffic i will stay in the right lane and stay far back from others.... people will pass me respectively and theres no rocks or anything being kicked up.
