10. On-Board Toilet

The on-board toilet in cars has actually been tried out in the past, but has never really found a niche as a car improvement idea to sustain the test of time. One of the primary reasons that we have not seen toilets adopted in our daily drivers are the various safety and hygienic concerns associated with having a full-blown toilet in the automobile. Add in the issues with losing space in the vehicle for the storage tank for the sewage, and it’s likely that this feature will not be coming to our vehicles any time soon. Of note, Louie Mattar used an on-board toilet in his 1947 Cadillac to drive more than 10,000 km without stopping. There would be a big consumer benefit to having a toilet in cars today for the many times that one is stuck in traffic or going on a long road trip.
