Hitting a company with fines for not doing maintenance required by regulation, when the fines cost more than compliance, works well. Given sensible regulations, of course. Look at airlines: rather strict and reasonably good safety regulations made flying the safest form of transportation, safer than driving and maybe even walking. Nevertheless, we don't see exorbitant prices either; if anything, the cost of air travel is surprisingly low, often competitive with rail, even in EU. Of course, unreasonable regulations are a bane, see the leaded fuel situation in general aviation, or the whole nuclear industry.
