Thank you, UltArc!
It is not a challenge with fueleconomy.gov if users access the page on full-size computers, but it is a bit challenging for first-time users if they use mobile devices. fueleconomy.gov is designed for full size web browser, and it does not redirect automatically to fueleconomy.gov/m.
Since this is the first app that I published, I think this is a good starting point.(so I can add more useful functions later on)

Comparing vehicles on the application is a great idea! Thank you again.
