This is one of the major is issues in Thailand... borne of an utter apathy by the police to enforce the laws... people do what they want when they want (i.e. park like this) then the sense of entitlement develops, they expect to park like this all the time.... No one does anything...
Pedestrians are forced to walk on the road.... Its the same with motorcycles on the pavement, ‘someone’ even goes so far as to add a little concrete and build little ramps to ease access !!
Do those in positions of decision making power know ??? My guess is they care so little they hardly notice until something negative occurs and social media makes a big deal out of it... they are then ‘forced’ to care, but briefly until the issue dies down.
In this scenario, if you were looking for a spot to park and there was an available gap, what would you do???.... Personally, I’d park there, everyone else has... And thats the issue, the authorities ‘enable’ antisocial traffic behaviour (and parking) by doing nothing about it - in this case they’ve pretty much designed the pavement to be parked one with the ‘ramped kerb stones’....
That said - is the side walk / pavement on the other side of the road clear to walk down ???
This is one of those... TiT issues... not too much to take issue with, its just one of those things to shrug at... its Thailand after all.
