Mechanical Engineering Final project title selection?

I am final year student of BE mechanical. Can you suggest me some new innovative ideas related to automobile (2 Wheelers) or hydraulics or any kind automation projects.

The two wheeler population is increasing like ants. Reducing their weight would have a beneficial effect on the environment.

See here if anything can be attempted with this polymer:
