I think these two Metros parked within spittin distance of each other shows that someone is either collecting Metros, or, bought a back up for parts to keep the best one running

using spare tires for both front tires? Is that weird? Or make some logical reason I am not not aware of? 

I don't know what RTPS means in context of miles per gallon.

the internet acronym finder has these suggestions for RTPS:  https://www.acronymattic.com/RTPS.html

and the one that makes sense is Rear Tire Protection System ... as in it's a front wheel drive that won't spin the rear tires because the engine is so low power it couldn't spin any tire
