A couple of other things to keep in mind:
1 - you will need 220V lines; and,
2 - dust collection is a must-have for this and will restrict your ability to move things around.
Combine those two and what you will probably end up with is a fixed position (or nearly so) for your table saw and a plan to move at least one car out when you need to use a large mobile device like a planer, jointer, or shaper - just put those on wheels and park them near the door on "your" side until you need them.
Further.. if your garage is long enough you might consider running a fixed work bench with drawers along the whole front - this will give you storage space and still let you work with at least one car in the garage.
And, incidently, don't let the sawstop pro or con people influence you too much - it depends on how careful you are and whether you need to buy insurance because others are going to use the saw. Sawstop is worth its weight in premiums.. and the extra cost if you're the only user can be thought of as a premium you pay to protect yourself against yourself.
