In general we seem to have a media/politically driven issue with "studies" being trotted out to try to influence a particular course of action rather than as pure information dissemination. It's not an issue with "trust in science/scientists" in as much as it's an issue with information flow being controlled in order to produce a narrative, and people can see through that. Science is - we've done the maths, we've done the study in the wild, if people drive at 25mph then we get N% fewer accidents and M% fewer fatalities from the accidents that do happen. Politics is - we're enacting a speed limit, putting cameras up and making the fines punitive in order to force you to do it. The former is far less controversial than the latter.
