i think this is silly
if you have friends, or family
or a date
or anyone that needs a ride other than you
or you need to move houses
or you go get a few pizzas that wont fit in the small compartment on a bike
or anything at all going on in your life where you cant commute by train and bus you probably need a car
Ehhh a few points are car dependant, on the other hand some ain't
If you need to transport more than one additional family member/friend/loved one then I guess you're screwed, but on the other hand you can still transport a LOT of cargo (Depends on bags for your bike and kind of bike) with my future Honda CBR650R I could probably transport six family sized pizza's.
Moving places is kinda eh? I guess most household items are easy, a PC and monitors are "manageable" with a big box on your backseat, but we all can agree that tables and other furniture is (legally) impossible to transport with a motorcycle.
Commuting in cities like Munich is WAY better with a motorcycle, as with a car it sometimes gets really tight in certain streets making your drive an absolute nightmare (probs comparable to other cities around the world)
A bike, depending on what purpose you bought it for, can save you a lot of fuel costs/maintenance in comparison to cars, insurance I can't easily compare (do that yourself), and most regular even premium bikes (Yamaha, Kawasaki, HONDA CBR500R/F/X, etc.) are more affordable than regular cars (Mercedes, VW, Honda, BMW, etc.)
Commuting with car is more convenient I guess, but a motorcycle just feels
different. They both have negatives and positives, and I decided to go with a new motorcycle in the same price category as a used/older car.
