Only Ricers do. Why? Because they lack the ability to realize nearly every manufacturer these days has some form of variable valve timing and/or variable ignition timing.
It's just the most talked about because Honda introduced the system early and cheaply into small compact cars everyone could afford unlike other manufacturers who only installed their variation of it in their higher end cars in the past. Also because every high schooler (and Fast & Furious wannabe's) who own a Honda with VTEC thinks they have the fastest car in the world so all they talk about is VTECH, V-TEC, VTAK, VTEK, VTEKKKKKKKKKKKKK.
Quite annoying and it gives me and countless other real Honda enthusiasts a bad reputation we're forced to deal with. All in all though, with all the years and research behind it Honda has made a very reliable, cost effective, powerful, and smart variable valve timing system capable of power from such a small engine others can't possibly match.
