Despite the LTN measures, Kings Heath High Street remains a private car sewer, making for a high street with high levels of pollution that is hostile to active travel. It has been shown the world over that such conditions suppress trade in shops along the road by about 20%. These drivers are probably heading for Lidl, but thanks to a modal filter in Silver Street at least they are now not abusing the back streets of Kings Heath, as used to be the case. That makes it possible to visit Lidl on a bike without having to dodge cars on narrow streets.
