Of the ridiculous number of vehicles currently on the road worldwide, the vast majority of them are not brand new models. Considering the fact that the biggest increases in fuel efficiency, safety and emissions have taken place in the last few years, the legacy vehicles still on the road are a big concern. While it is easy to suggest that we remove these vehicles and replace them with newer models, this is not always practical, so some are suggesting that these vehicles be equipped with retrofit technology in an effort to save fuel and reduce emissions. One such technology could be tire pressure monitoring, as under-inflated tires make a big dent in overall vehicle efficiency.
While the idea of adding technology to older cars may make sense, the realities of making the change are rather difficult. The European Commission's Directorate General Enterprise and Industry head Philippe Jean suggests that it is much easier to regulate new vehicles rather than old. What's more, all EU member states would need to agree on whatever regulations are suggested, which would likely prove rather difficult. In other words, don't hold your breath.
