Medyo OT pero share ko lang almost same experience ko.

I'm driving Sentra way back 1997 along Batangas-Laguna National Highway on way back to Manila. It was noon time and I'm cruising (50-80km/hr) on inner lane while a jeepney is on my front. Not much traffic at that time then all of the sudden the jeepney on my front make a fast change lane going outside. This was very brief and when he cleared the lane I saw an incoming ambulance right in my front with all his emergency light flashing. Without any thinking and without looking if the other lane is clear I pulled my car on outer lane and thanks God I made it safe. For few seconds I was speechless and stunned so was my fiance sitting on passenger side.
Should my luck doesnt play good that time and I got a head-on sino kaya ang may kasalanan?
