Don't believe everything you hear :-)
Think about it: if you're going to make a flying car, it either has to have wings like a conventional plane, or rotors like a helicopter. The winged version is going to need some sort of runway to take off and land, so you can't just land wherever you're going. To drive around on the highways, you need to fold the wings somehow, plus you're carrying around the extra weight of wings & prop when driving. You also need a drivetrain & steering, which is going to be parasitic weight when flying. You've got a machine that needs to do two very different jobs, which means it will do neither of them well.
Helicopter-like? Well, consider the drawbacks of helicopters now: high fuel consumption, blades spinning at high speeds, &c. Now make those blades stowable, and add the weight of transmission & steering...
