Nah, unlike a car, the pedal in the middle is the first one to get cut. The damper, or sustain is on the left, and it is absolutely necessary. (It’s one of the chief differences between a piano and a harpsichord - you just can’t play much post-Haydn/Mozart without one.) The una corda (far left) does different things depending on your piano’s design. On grand pianos, it shifts the hammers over so they only strike one string per note instead of 3. On most uprights, they change the position of the hammers so they are closer to the strings, reducing the amount of force with which they can strike the strings. Less force = softer sound.
The middle pedal is a sostenuto on full grands, which allows the pianist to play a chord, depress the pedal, and only the notes of that chord will be sustained. Some pianos have a middle pedal that will sustain only the bass notes. Some pianos have a middle pedal that’s just there for decoration, and some don’t even have it at all.
