I agree with the sentiment of the original poster!!!
I also find it funny how the use of adjectives to describe your preferred mode of transportation changes depending on your perspective.
We are car people, but after seeing so many posts on this board about how 'relaxing' the buses are, we decided to forego a rental car on a recent trip. HUGE MISTAKE!!!!! We were miserable that trip. So much so that I tried renting a car while on the trip itself, but it was too costly.

I think our two biggest mistakes that trip were trying to go from resort-to-resort using Disney buses (90 minutes one way) and visiting DTD two nights (45 minutes one way). But even without those issues, getting to/from the major parks was still painfully slow for us as we knew how much faster a car could be.
On our most recent trip (June 2011), we rented a car and were so happy. It made our trip much more enjoyable and relaxing. It will now just be part of our vacation budget. Thank goodness, rental car prices seem to be going DOWN! We've had some great deals recently on rental cars. They seem to be better the closer you get to your vacation.
I don't think you can stereotype anyone as to whether or not they will prefer buses or cars. I commute to work everyday in heavy traffic, yet I still prefer to drive on vacation. WDW traffic is nothing compared to rush hour. Plus, I love those purple signs with Mickey Ears that say "Magic Kingdom Next Left", etc.
We don't find that we have to be in "100% control", but instead look at a car as "freedom" to move about as we please.
We find that the roads around WDW are well-marked and easy to get around.
We have never experienced traffic congestion at WDW. It is very easy to get in and out of the parking lots. Parking lot trams are very frequent and quick for those days we arrived at the parks too late to get a spot up front.
Travel time is significantly shorter driving versus buses even after factoring in the parking lot tram. The only exception is driving to the MK, but when we are not staying at BLT, we prefer to enter the MK via monorail/ferry the way the imagineers intended. Plus, exiting the MK at night is often a toss-up on time between a car and the buses.
Disney buses tend to travel slower than car traffic. We always pass right by lots of buses heading to our destinations.
When driving, there is no extra waiting for the buses to load
ECVs or make multiple stops before getting to your final destination.
When driving, you don't have to worry about other guests being rude (cutting in line, getting on the bus through the back doors after they load an
ECV even after the bus driver has yelled to stop it several times, etc.).
When driving, there are no issues with getting a seat which is nice after walking and standing in line all day. The last thing I want to do is stand in line longer for the buses than I did for Splash Mountain.
After such horrible bus experiences, we know we are truly car people. I'm glad there are so many bus people though as it helps keep rental car prices low (i.e. lower demand) and it keeps the roads less crowded around WDW. So for those on the buses, keep riding them!! But for us, we will always be using our car.
YMMV
