This is why I use a GoPro whenever I ride on the streets anymore.
Having recently spent a lot of time researching the proper way one might grocery shop with their bike, I actually heard of many different ways to shop for your groceries by bike. I personally use some Thule Panniers I got from BikeBagShop.com for an amazing price, but others came up with other inventive ways that included using an existing kids trailer, using a Bob style trailer or making panniers out of kitty litter plastic containers mounted onto a bike rack. What no one suggested, was to put your groceries in a grocery cart and ride with it at your side, maneuvering across six lanes of traffic, and then into oncoming traffic on a busy stretch of road as you will see in the two videos. Its safe to say, safety is not a priority with this guy, but getting the groceries home in a speedy manner is.
