According to the Driving Instructor Blog, there are a few reasons why people can’t make a corner with their vehicles. “For example, many new drivers when they’re turning left, instead of looking at where they’re going while they’re turning, they’re still looking at some oncoming traffic that is down the road. If you’ve decided to turn, then you’ve decided it’s safe to turn in front of that traffic; so what’s the point in staring at it anymore? It’s not like you can turn halfway and then press pause and reevaluate your decision. So essentially you aim your car where you look. If you’re still looking at the oncoming traffic while turning left, then your car will tend to aim towards the oncoming traffic, leading to a wide turn; as oppose to simply making a safe decision to turn when you see a safe gap in that traffic, and then looking where you actually want the car to go and then going there.”
