If I try to push 1C into one of my cell phone battery(actually a single cell) with my charger, it tops out at 4.2 volts in just a few minutes from after the cell phone shut itself off. At .5C , the battery has a more respectable charge curve. They don't take high discharge currents too well but do it better than they do at charging. I wouldn't pull more than 1C from a cell phone battery if you want it to last, I'd probably stick with enough capacity to where I'm pulling .5C. ...I wouldn't imagine using these in a car, they are cheap cells that only last for 2 or 3 useful years in a cell phone if you discharge it once a day with plenty of data or wifi usage. ...or some phone can barely last a day in the first place not to mention after some degradation with cycles and age. Same goes for laptop cells, they are designed for energy density and form factor, not life.

Yes you can't make a car, but I guess you could make a battery pack for an electric bicycle. Or I could use it just for energy storage, solar, wind. I bet we could find these batteries a purpose!

The thing I'm doing now just for the fun is attaching an alternator to my home fitness bicycle. Get a battery to it and attach diodes. It would definetelly stimulate me doing more fitness
