I saw that. But you understand the argument you're not paying full due care and attention to your driving if you're blabbing on about something you consider to be impressive (whilst in control of a moving motor vehicle)? We all make risk assessments countless times each day. If you kill someone whilst driving, you and others will have to deal with it. Kill / maim just yourself? Well, you obviously seem to be okay with that. My concerns are primarily with those 'others', naturally.

Spare a thought too for the impressionable people who look up to you? You are a whale, after all! Maybe you are the ultimate driver but maybe others who are not will choose to try emulate their idol, inadvisably? Ask yourself: Does it improve your driving safety? Is it essential for your job (you don't look to be a cop or a robber)? Are you so selfish you're happy to continue having answered no to the two previous questions?

Please tell me, you're not driving right now. :) And people driving on youtube with their fancy hands-free kits doesn't really make it any more right, does it?
