Are Hybrid cars really worth it in the long run?

b_rei7 questioned:

Does the bonus cash frank for a more fuel efficient car really make fiscal implication in the long run if gas doesn’t go up more than $0.15 a year?

Will I get any net savings from buying a hybrid car?

indiano questioned:

Take into tab: the superfluous premium I will be paying frank. If so, recommend a hyrbid. Also, what’s the payback cycle, if any.
