You did clear it up, except relatively rare does not mean that.<p>You can&#x27;t make up new definitions for things and expect people to understand you.<p>Relatively rare has the same meaning as rare, except that it&#x27;s rare only in comparison with the compared event, but might not be rare on an absolute scale.<p>So, no, 49% is not relatively rare.<p>1% is relatively rare, yet 1% of car trips is still an enormous number so is not actually rare. That is the only change in the meaning when you add the word relatively.<p>Getting back to your actual point, which was derailed by an incorrect word.<p>Multi car trips are less common, but not enough to make single passenger vehicles economically worth it. The majority of the expense on a vehicle is not the cabin. Once you paid to make a car, adding a bit more space for additional people costs only a little bit more, but greatly increases the flexibility.<p>So I don&#x27;t expect the basic size of a car to change much.
