It goes without saying that the data they gather on their vehicles is useful. But it's only useful in gathering data for existing passengers. 
Not data from the ones who have moved on or never touched public transport in the first place. 

The proportion of people using public transport regularly vs the proportion that don't, shows how many views/opinions/needs aren't taken in to consideration when these changes, revisions or tweaks are made. 
A pro-active operator would seek these out at whatever cost*. Because even a small proportion of car users switching to a viable alternative, not only makes helps those profits, but it has a huge positive impact on reliability.

*I'd hazard a guess the ROI is far greater than titivations ever were.
