outruns a bicycle for shure
Every top-tier car can outrun a motorcycle. The only reason motorcycles may seem to get to places quicker is because they have a significantly improved initial acceleration (due to their low weight and high engine output) and because typically the bikes are smaller and thus the riders can take more shortcuts through traffic. Get a bike and any of the super-cars on the open road, and the bike is going to get creamed as they don't have the top speed or gear shift ratios to match.
rocket voltic is best car.
overall rocket voltic is best car. its favorite car. mcjooble has nothing on the rocket voltic.
The only thing that makes the Rocket Voltic so "good" as a gimmick car is the rocket itself. The Voltic is the worst super-car in the game, outpaced by just about every sports car, let alone its direct competitors in class. The Rocket might be good when you're loving around in the open world, but its practicality in missions is severely reduced; the Voltic's body shape means the driver is far more exposed than in other vehicles (like the X80), the rocket is far too uncontrollable for precision driving (such as when you need to run a goon down without destroying the cocaine sitting right behind him), and once that rocket powers down, you are relying on the Voltic itself, which as I mentioned is one of the most pathetic excuses for an exotic car in the entire game.
If you take away the rocket, any one of my sports or super vehicles can demolish you. Hell, have the rocket and try to do A Titan of a Job, Base Invaders or any of Gerald's missions with it. And this goes for any of the over-priced garbage that came with Import/Export; the only vehicles that were actually valuable contributions are the Tempesta, which is the third fastest super in the game and one of the best handling as well, the Elegy Retro Custom, a magnificent tribute to the Nissan Skyline and is as fun to drive as it is to customise, and the Comet Retro Custom, which is just like the Elegy but much faster.
The only "gimmick-car" that actually turned out to be useful and beautiful is the Armoured Kuruma, which got a boost in speed, is almost completely impenetrable and has a mass factor so high that it can knock away trucks with ease. That car's gimmick is practical, rather than ridiculous.
