Ah - the beauty of the "free market." Everybody gets to buy whatever they want and use it whatever way they want to.
Touch screens in the front dash of new cars - great idea? 500-watt portable boom-box speakers to share your "music" in the wide open spaces - great idea?
Aw never-mind - no one a gives a sh*** - turn on your 2000 lumen blinky and plug up your ears with ear-buds so you can bomb down the bike path at 40kph. Money dictates who the cool people are.........
