Already happens in most cities in South America I've been to (and in Caracas, where I grew up). They sell all kinds of stuff: snacks, jewelry, car freshners, cold soda/beer (they carry around little coolers -- and yes, they sell beer to drivers), pirated dvds, etc. Also, juggling acts and car washes at lights... Sometimes, even if you don't want it, they'll wash your windshield so that you're guilt-tripped to pay them something. If you disallow them (by screaming at them), they may mark your back windshield with some soap. Later down the road they'll rob you if they see your car bears the mark. This means you have to get out of your car and clear it to be on the safe side. Truly annoying...
