Annoying day to day life

Expedition v. Excursion

ex·pe·di·tion/ˌekspəˈdiSHən/Noun
1. A journey or voyage undertaken by a group of people with a particular purpose, esp. that of exploration, research, or war.

ex·cur·sion/ikˈskərZHən/Noun
1. A short journey or trip, esp. one engaged in as a leisure activity.

This gets me, it really really gets me. Expedition means a bigger trip, excursion means like a day trip- a smaller trip. So then logically, an Excursion should be the smaller car. Expedition means a bigger undertaking, and should therefore be the larger vehicle. But no. They are reversed and it makes me freaking insane. Really, I see one of these cars on the road and I want to yell at Ford.
