Umm, pot meet kettle. How many parts have you produced that other companies already sell?
Also, are you really gonna defend Driveline's "Slingshot"? You do realize they got their idea elsewhere as well, right? Gigot is the original Slingshot, not Driveline. Driveline just has the capability to produce them in mass volume to handle market demand. That's how business works. I don't advocate it, but it's the reality. I only have a problem when someone is blatantly ripping off another product and attempts to undercut them and compete directly with them. That's when it is shady.
