Japanese cars are great. But so are some American and Korean cars.
As for two-wheelers, I just love them. Even leaning through curves at 25MPH is hugely fun. One cousin races motorcycles semi-professionally up in Washington State. He rips around tracks at 150 MPH or faster. I love talking bikes and cars with him. Though he loves the track, he really enjoys taking ordinary bikes out and riding at the speed limit. He just wants to be on two wheels. I totally agree.
I don't know if it is true, but some say that riding a motorcycle requires as much skill and attention as flying a jet fighter. I haven't flown a jet fighter, but a motorcycle is entirely engaging. Just you and the road. Always fun. Though I don't recommend it to younger people. You nedd the protection of a car for a few years to learn how to read traffic. You'll get a sixth sense about what other cars are going to do. You have to understand that before you make yourself vulnerable on a bike.
Very true, you have to have a safe reliable "real" car for back up.
