Can you explain more by what you mean with it is a "good company"? It is not a good or bad company, it is a company which mission is to make money.

Shorts help keep the stock market healthy by giving opportunities to investor to invest into overevaluated stocks. And honestly Lyft seems to be a perfect candidate for this.

Probably should have been steamrolled by Uber but managed not just to survive but to thrive. One key to success is that many believe the product is better, at least in part because riders and drivers seem happier. Very fast growing and huge revenues and gross margins. Along with Uber has pioneered a very successful and desirable transportation category. Good enough to complete a good, successful IPO.

I don't see much health value in ability to short over-valuation.

That's a very Elon-esque understanding of what short pressure does.

So what does short pressure do and how does that relate to the sentence you quoted?
