i heard that, in some locales, if you don't turn your head to look, bagsak ka sa driving test. is this true?
because if it is, then we still have to turn our heads, even as we already have our licenses.

alam ko sa california ganyan kasi nasabihan ako ng DMV officer nung kumuha ako ng driver's license, need talaga lumingon before changing lanes kundi bagsak ka.

sa saudi naman baliktad. when backing up/reverse di ka pwede lumingon sa likod, side mirror and rear view mirror lang. pag tumingin ka sa likod automatic bagsak ka na.
