The driver showed absolutely no willingness to stop.
He did his best to get in front of the pedestrians who were already crossing the road, rather than stop willingly to let them finish crossing.
So, they had to walk in front of a moving car or be forced to stand and wait in the middle of the road to let the car through, then suffer the same challenge with the next Thai driver.
But rather than stop completely, the driver then continued to roll slowly towards the group as they crossed getting uncomfortably close to them.
This was probably to hurry them along or to display aggression towards them for crossing the road.
It's a game to the drivers here, I think.
Probably something to do with losing face as well.
I had a similar experience yesterday with a taxi on a crosswalk.
