Tripsense is a usage-based insurance program that encourages drivers to drive safely in order to reduce their insurance costs. This means that drivers are incentivized to drive more carefully knowing that their driving patterns are being monitored. As a result, drivers are less likely to engage in risky behavior and therefore less likely to have accidents, resulting in lower insurance costs. Option A is incorrect because even safe drivers would want to take advantage of a lower insurance rate. Option C is incorrect because drivers are incentivized to drive safely, not recklessly. Option D is incorrect because the program is designed to affect driving behavior.
