I think if someone your size got out of a Honda Jazz the other guy would just die from the shock.
Parking bay widths vary depending on the use of the premises. For example, the narrowest spaces are 2.4m wide for long term parking at offices and such. High turn over parking at shopping centres is supposed to be at least 2.6m wide. I can guarantee that wherever you are, the architect designed the minimum width spaces so they could fit more in. And 90degree parking fits more in than angle parking so the only time it is used is where there isn't enough space across the car park for full length parking bays and an aisle.
