Touchscreen Windows in Trains Becomes a Reality

It was with some interest I read the other day about plans for touchscreen windows on the new High Speed 2 trains which will be travelling at speeds of around 225 mph. The windows and doors will have 'smart glass' in them so we'll have the opportunity to bring up information on our journey; current destination timings for example or more interestingly, details on the numerous landmarks as they flash by.
Perhaps there might even be some kind of food or drinks menu not dissimilar to the in-seat service you can order via your TV on Air New Zealand flights.
Either way, the technology is in place now for us to use smart glass touch screens to make our journey's more interesting.
The thing that bothers me, as someone who leans towards OCD tendencies, is having to swipe my fingers over glass a thousand other people have used. I can almost see me having a box of wet ones next to me whilst reading a magazine on the window next to me.
HS2 has come in for all kinds of flak but frankly anything that reduces journey times these days must be taken seriously.
