I drive a semi around a major metropolitan area 8 to 10 hours a day, the vast majority of people have the minimum amount of common sense to not get into a bad spot around large vehicle, once in a while someone does something that simply boggles the mind.
I've been in the industry over 25 years and can safety say turning incidents are uncommon and usually require both parties to not be paying attention as trucks take turns of this type at very low speeds.
