I love to drive and my car is paid off, so eventhough I only use my car on the weekends for errands and visiting friends and family I will not give up my car -- I know it is an expensive toy to have.
I find that car owners are more and more the shrinking minority, which is great for the environment and relieving urban congestion.
I like to see the number of parking spaces be reduced in condo developments, but not totally eliminated, as owners of large and/or expensive units will most likely own a car and people spending over a particular price point expect to have parking. Having on-site car share vehicles would be a great amenity, and also providing plug-in terminals for each parking space for electric vehicles as they are becoming more popular.
Having resident and visitor bicycle parking spaces that are easily accessible is also a great amenity to encourage people to ride their bikes more. I have seen bike parking located in obscure areas in a condo or even not even on the ground floor, which makes it inconvenient or a hassle to park or retrieve your bike -- people would rather lug their bikes to their own unit, which is often against condo rules.
Having a security camera in bicycle parking areas would make people feel more at ease parking there, as theft and vandalism are more frequent with bikes than with cars.
One great feature I have seen on a couple condos is having a maintenance area in the bicycle room for an air pump, basic tools for minor repairs and a water hose to wash off your bike.
