But, why would you want to object if you have nothing to hide?

I'm not usually the person to say things about things like this. I'm all
for ID cards and the like, but the fact remains that train travel should
always remain an "open" thing, not to mention the embarassment of being
the one chosen amongst a group of friends.

IMO, if this was rolled out full time, surely it would pose a greater
safety risk, whereas before, everyone was dispersed around the station
and trains, HEx travellers will be more concentrated.
