It is shocking to me how expensive the roads are in France, and you don’t get any quality for it either
And that's despite having very heavy traffic including a huge portion of heavy trucks transit across Europe.
Same question for the countries where it is state-owned and cheaper.
The motorways are run by private concession companies, which is why each stretch has its own booth price.
Free alternative are the N and D roads, slower but toll-free, which is often how locals do longer trips on a budget.
The expectation that the service gets either better for the same amount, or cheaper for the same service, is usually naive
