@MartinSLewis Hi Martin, Packaging Consultant here (yes really). The real problem is that most folk dont use the caps correctly, & itβs not intuitive as to how to use them (Iβd need a longer post to explain). Technically it works as intended, but folks, quite understandably, just dont get it.
@LindaR39 You do realise that itβs an eyesight test every three years, rather than a driving test, dont you? Please do let us know what your MP says.
