the article says that it’s more difficult to use this turn signal in the roundabout ( as the button is on the wheel so its position shifted along with the steering wheel, as opposed to the static position of the stalk ) and the driver has to shift a part of their attention to locate the button The person who found this also ask other instructors and they agreed, that’s why they’re not buying this model

but IMO if I’m an ownwer of a driving school looking to buy new cars for students, I’d pick more generic one too. Students would prefer to learn how to operate most cars than a specific model. Like how most music school would prefer normal guitar than double neck guitar
