Okay, take for instance a Texas Beach. You just got out of the water and get semi dry. Throw a towel in the seat and choose to roll down the beach a bit to look for birds bombing the water, or in the surfer case a better break. You are cruising down the beach driving a straight line at a pretty slow pace. There is almost no chance of getting t-boned from over the dunes or from the surf. The seatbelt would only soak up water from the trunks. So I don't really think I need a self destruct warning to hender my enjoyment of my cigar, tranquility of the surf, music. You tend to drive scooted to the front of your seat hunched over your steering wheel with your gaze on the water, chest just inches from the wheel. A seat belt just doesn't work in that situation.
Also, I live on a culdesac. So I usually back out and start driving down the street before I fasten, and I do. But for it to be ringing an apocolyptic tone at me before I get two houses down is outrageous. Granted, I'm not used to the rig, I still have paper tags at the moment having just traded in my Gen 4. I'm not opposed an alarm, just let it go away rather than the whole thermo nuclear reactor meltdown obnoxious bas**** alarm that it is.
