Very entertaining but I must protest  Gaushala is by far the worst traffic bottleneck in Kathmandu these days. The place has inflicted enough suffering that I can't bear to see any other spot in Kathmandu steal that honor. I think Chabahil  has  improved somewhat after they tore down a few buildings, widened the roads and deployed more traffic cops in the area. Unfortunately, with all the religious and heritage sites in the Gaushala area, me thinks they will need to dig a tunnel to solve the problem there. Then there is Teku of course - the mother of all bottlenecks followed by the Thapathali bridge. Come to think of it, you would probably have to go outside Kathmandu to find a place that isn't a bottleneck during rush hour.
