When I crew it takes a few minutes to adjust the seat and harness anytime we have a driver change. The genius of the modern three point seat belt is how easy it is to put on (comparable to lap belt, yet much more effective), how comfortable it is to wear (with the advent of the spool and height adjustment), and effective (due to seatbelt pretensioners).
