The US has similar laws. I used to work for third party scan tools, in 2006 every manufacturer was giving us information. The big companies made them available for "a reasonable price" which I'm lead to believe was in the range of 50000. The small companies gave it away and begged us to support them. (small companies knew that if their car broke down in the middle of nowhere the only mechanic would be independent and so they wanted every mechanic to have a chance, big companies knew every mechanic would want to work on their cars so they didn't care to make it easy)
