Picchio Special is correct in is definition.
We have had this discussion about 4 times in the past 20 months. I still enjoy the debate.
What must be remembered is that it is an historical term and needs to be interpreted in context - a number of posters say "My interpretation of Path/racer is.." or "I think it's this.." . It doesn't matter what someone 'thinks', it is what it is. This is, of course, being pedantic, but we might as well be acccurate.

Many of us strip down pedestrian roadsters and do'em as as immitation Pathracers. That's fine, so long as no-one tries to pass it off as the real deal.
