We need the money being spent on the infrastucture, as much as we need nurses, midwives, etc.
It's not about shaving 5 mins off the commute. It's about ensuring that all the things we need are transported efficiently, as this reduces the cost to us in the long run. Being held up in a jam adds to the cost of the fuel being used by all those lorries, which in turn pushes up the price of the goods you need. If the roads are better the lorries don't use so much fuel, and this also has the knock on effect of cleaner air.
And another thing. In my home town, we have been trying to get a ring-road or bypass for many years. We should have had one by the mid-1980s, according to the reports we had then. In fact my parents remember a campaign from before I was born to get a bypass built, and I'm 40+ now.
Even now, it can take 20 mins or more to just get across town, a distance of about 1.5 miles, especially at rush hour. And yet the bypass never gets on the drawing board, but the council has just announced plans to build 1000 new houses on the north side of town, and the plans make no provision whatever for improving the transport links. It's going to be a sodding nightmare for us, on the south side of town, to get across to see MIL on the north side, even at quiet times.
If some of this £30billion can get us a bypass, it would go a long way to making our town more accessible and perhaps businesses might come here, when I know some have been put off moving into the town because of the transport.
