Compared to what I have encountered in India, specifically Mumbai, the video has shown a rather light traffic. Milan traffic can be deadly (in 2h I have seen 3 separate accidents, where passenger compartment got virtually eliminated), but by far does not get as complicated as in India. In Mumbai, the vehicles commonly form a single medium with inch separations between vehicles and yet move nonetheless, not necessarily in the same direction. Vehicle groups accelerate in synchronicity, as seen in the video, but continue to do it at much vehicle densities, with the vehicle medium rarefying, compressing, mixing, etc.

I recall a State Dept directive asking Americans not to drive in India, as a relatively high number has apparently died in trying to cope with that complicated traffic. Also, I know Indians who own cars but hire drivers to drive them around, when in need, as they do not trust their own capabilities. Within the short time I had there, I did not try to ride a bike.
