Another hideous example of what happens when you mix transporting people with transporting freight.
Seriously, if you can’t build the necessary rail infrastructure because Australians today are less capable than our ancestors 150 years ago, can’t we at least build freight trucks a separate road or something? Get them away from cars. Everyone who’s driven up the Hume has experienced some twinge of concern for their family and friends as one of these monstrosities hooned past. Trucks and cars do not mix well.
PS When doing your cost calculations for this, please remember to factor in the lives saved.
