That looks to be 2" thick. You should have 4" for cars.

And probably a good bit of draining rock beneat the concrete to limit the damage from freezing soil.

What is the depth of the rock bed? 6", 8"?

We used 6" thick with the proper amount of rebar. This was 30 years ago and only have a few hairline cracks. This was for a parking pad.

I've seen 4" recommended for cars and 5" for heavier vehicles. Obviously other factors go into the design and the local construction companies know what works for the area. When you had it done was that the only option or could you have gone thinner?

The contractor who did the job was a neighbour. He built my double garage 2 or 3 years before and wanted to bring the pad up to the same level as the garage floor. He said that it would stand up better to frost. Canadian prairie winters. The important part was the rebar. He laid the proper amount of rebar and I got the job of tying them together with the wire twisty things with the hooked tool. He was one hell of a contractor.
