Is private transport (i.e., the construction of roads) even financially sustainable? I did a quick search and it appears in the UK the amount brought in from vehicle tax each year is less than the amount spent on roads (https://www.gov.uk/government/statistical-data-sets/rde01-ro...).
Transport is massively profitable for the economy but not for the transport companies themselves, they simply can't capture enough of the value generated to turn a profit. If they try then the level of transport disproportionately goes down to make them lose even more money. It's why most/all of a public transport needs to publicly funded in some way and saving a penny or two per ticket on WiFi will cost far more to the economy than it saves.
There is one notable exception. Japan's train system is profitable depending on how you look at it. The trains themselves are a "loss leader" in that they actually lose money per train ticket, but the company that runs the trains also owns the terminals (lots of retail space) and the commercial real estate around them, which is where the money is made. They are in effect a commercial real-estate holding company that's doing transport on the side to beef up their portfolio.
Well, yeah. Public transport never going to be as sustainable as private transport, that's why the government is funding it in the first place. It's partially to provide tax payers with a service, and partially to offer an alternative for those who can't afford other options.
Whoever put punctuality, personal safety, and train Wi-Fi in the same part of the questionnaire was setting the research up for killing the Wi-Fi. Obviously people prefer not being stabbed on the train above Wi-Fi and "arriving at the destination on time" is the main purpose of the whole field.
"We want commute to be worse and more expensive" is a bizarre take to have as the department of transport.
