I agree with you and think it's worrying. I, too, accept that we're leaving, but really the work has only just started. One of my many reasons for wishing to stay is that the EU offers UK citizens some protection against its own government, which is a pretty sad state of affairs. That's why I'm glad we have the likes of Clegg and Starmer keeping an eye on what's happening. I wonder how many people really understand the implications.
I also find the 'secret deal' with Nissan quite worrying. I'm glad for the people who will keep their jobs, but I also think cherry picking is the beginning of a slippery slope to nudge nudge wink wink backhanders.
One way or the other, I suspect we're heading for 'hard Brexit', which is almost certainly going to be a disaster for the country. The remaining EU countries really don't need the UK that much and the chance that they will allow us any special deals with the single market are almost nil. If it means that banks, other financial services, IT companies and pharmaceutical research move to other EU countries, the UK is stuffed. And then there are the Ireland and Gibraltar questions...
I don't even think it's possible for people who voted Brexit to get what they wanted (whatever it was).
Fortunately, UKIP is doing a pretty good job of destroying itself, but that won't destroy the motivation for voting for them. What's happening in parliament at the moment is as much about political parties in disarray as it is about steering a course which is good for the country.
