I get it, I do. It is the same issue we have in the US. It takes time to build this stuff out. There is a LOT you CAN get to right now and even if you can't get where you would like to go that one time a year, there are many other great places you could go instead.
The example I can give is from my own personal experience. The ONE place I REALLY want to get to I can't. Which is middle-of-nowhere Ohio (near the WV side). But, in the same sense I have made 4 road trips all but one of which was to places I had never been and all of them were for reasons that would have needed a TON more justification otherwise.
And it isn't like it won't ever come. I should hypothetically be able to make it where I want to go sometime next year (assuming they stick to their current plans) and I am OK with that.
If I REALLY was despairate to go, I could rent a car. But I wouldn't trade the past 24k miles over the past year of awesome driving just for that one weekend trip I would have made once... Maybe... Over that same year.
If what is stopping you is that one RoadTrip you might not even make, don't. You will be able to be there sooner or later it is a matter of time. In the meantime you are passing up something truly awesome. And don't just take my word for it. Realist, one of the biggest naysayers on the car has changed his tune completely and that is more powerful than I could ever be.
