Not all exploration happens on foot. On Sunday I was in a car slowly getting out of the city centre to go for a Sunday drive in the inner and outer suburbs but the entire grid was clogged. There was no quick way out, we just crawled long until just about where the post-war city starts, then things started to move. I instagramed a screenshot of the google traffic map at the time (about 2pm on Sunday) and Spacing contributor Amy Lavender Harris suggested the roads that are red — clogged with traffic — are the best to bike along because that traffic is so slow. Apart from watching for doors and pedestrians darting through the cars, it may be a useful consideration when planning a crosstown bike ride at certain times.
