ya lor, when my dad was in an ambulance on the way to NUH, traveling along Bukit Batok Rd and AYE, even with the siren on, people dont give way.
Sorry to hear about that. I can't vouch for the other drivers but in Singapore, sometimes it's not that the driver doesn't want to give way, it's just that there's no lanes/free space for them to filter into to give way.
