Huh? Spain definitely does not have orders of magnitude more motorways. It has only slightly more than Germany and France, and a little less than 4X more than the UK. A lot of this is explainable by differences in size; Spain also has over double the land area of the UK.
And keep in mind that "motorway" is specifically referring to what we would call interstate highway spec in the US. There's plenty of high quality roads that don't meet this spec that nevertheless would get you where you need to go quickly. In the US we have state routes and similar, and the UK has their own thing.
