So in other words, they only stick like glue at the track.... Track tires are unnecessary on the street. He could go one level down (i.e. BT-016, Diablo IIs etc.) or even two levels down (i.e. BT-020, Angel) and still have plenty of tire for the street, while also not having to replace them every 2,000 miles, get them up to temperature with a tire warmer or do a warm up lap just to ride anywhere. I think having a tire that suits the kind of riding you do is cooler than having "track take offs". My BT-023s are supposedly terrible tires, but they give good edge to edge grip in the twisties and never surprise me. I can push as soon as I leave my apt complex and know exactly what it's gonna do. That's the kind of tire you want on the street since you aren't gonna ever hit 100% or even 90% on the street anyway.
