Some observations:
There are street dogs, but way less than in Thailand. The only cat I've seen so far was dead alongside the road, hit by a vehicle.
I haven't seen any police, except for a caravan of Black Vehicles lead and trailed by police cars with sirens going and military types directing traffic to stop for the obviously VIP caravan. There are police boxes at the traffic circles, but I've never seen a cop in one.  I haven't seen a stop sign or a traffic signal, intersections are scary, but they seem to manage to miss each other.
So far I've seen scooters carrying all sorts of things, I saw a scooter go by with another scooter strapped to the back, a guy with a boxed dishwasher on the back, guys riding with long ladders, etc. I'll try to get some pictures.
Took a walk to the other side of the river on Sunday morning, not sure of the miles, but overdid it, calf muscles on Monday morning were so sore I could barely walk, stayed close to the hotel. Still sore today, but better.
