I think that's a bit different.
When I worked in polling stations a lot of people were nipping in on their way too /from the school run, or when walking the dog or similar, or had pretty much shuffled round the corner in an ad break or similar, so it's totally understandable they wouldn't have ID on them .
I am going to have to fit in voting on a day that involves - school runs X2, work, school runs X2., Sorting dinner, clubs for kids X3 and then heading out to work at the count..... I will hopefully remember my ID but will have about 8 million other things I am also trying to remember to do <grits teeth>
I am sure we will get used to it but it will be an adjustment for a while, like any new system
