T, 0-60 in 5 is slow, 0.85 g is not a lot, and 168 feet is a lot of space to stop a car from 70 MPH, also it depends on what car it is. if its a lotus, they lied, if it is a civic si, possible, if its a corvette, no problem, if its a mustang, possible, if its a camaro, possible, also depends on the year, if its a 1908 ford model t, hold on to a clock with out second hand to get to 60
