yes when the road is narrow, be it for whatever reason - a parked car on the left or a genuinely narrow road, how can you be for CERTAIN that you have or dont have enough room to carry on?
i had my 2nd driving lesson today, went on alot of busy roads and places - pretty cool for only my 2nd lesson - but was sometimes tentative when to go in narrow areas for fear of hitting the car to my right side, so my instructor would tell me to if i questioned or gently helped me steer it.
um i guess the question put simply is: when a road narrows for whichever reason, how can you be certain that your car can pass without it being hit?
