I saw this game on steam once and was like "Wow what a title for a game", looked into it and was interested in it.
This is a 3D platform collectathon, with the main selling point being no jump button in the game. You are a yellow taxi and go vroom, what else were you expecting? The game has its own special charm, I enjoyed doing 100% for the game and I recommend the game to those interested in 3D platformers.

The Yellow Taxi DOES INDEED go Vroom

While it may be partly my own fault, I can't help but view Yellow Taxi Goes Vroom as anything other than an unfulfilled promise. See, I really like 3D platformers, especially collect-a-thons, but have not found myself with a burning desire to play many of the newer releases in this particular sub-genre due to the fact that they, for the most part, tend to lack enough novel ideas to really differentiate themselves from one another. So when I first saw Yellow Taxi, with it's main gimmick of having to move the taxi with gas and break buttons, as opposed to the more typical thumbstick controls, I got excited thinking about all the neat ways car physics could be used to create some truly unique, fun levels.
Unfortunately, when I got to playing the game, I was quickly disappointed to learn that the level design in Yellow Taxi was more or less exactly what one would expect of a game of its type, with shiny objects scattered haphazardly across a couple of tiny maps that could have just as easily been in a game with a totally different control scheme. The reason for this is that the titular Yellow Taxi controls very little like a car and much more like the kind of zippy animal mascot one would typically find in a platformer of this style, just with the addition of tank controls. Now, I don't mind tank controls in my 3D platformers, and am actually quite the fan of games like the original Tomb Raider series, but the things that a game like Tomb Raider has that Yellow Taxi lacks are levels that feel built around that fact that the controls are what they are. With Yellow Taxi, even though the tank controls were a result of a deliberate artistic choice and not any technical limitations, the game and how its played would not change one bit if the movement was of a more common style, which I can say with absolute certainty, as the game does, in fact, change to thumbstick controls in several levels, which speaks to me of a lack of confidence in the game's core idea.
The only car-specific thing the levels have to offer are boosting over ramps to do jumps, which is basically the only trick up the game's sleeve, one it will pull out every minute or so, leading to all platforming challenges being mostly the same. Once you've successfully mastered the art of the ramp jump, the game quickly runs out of new ideas, which made the later half drag on interminably, a problem that the developers tried to solve by putting in a few lame gimmick levels. Why, in a game called Yellow Taxi Goes Vroom, am I forced to do a slow paced stealth segment? That one bit only goes on for a short time, sure, but it is indicative of a lack of vision that can be felt in most levels. A more common issue is the collectibles being placed just kind of wherever, with no obvious path to get at them. I would often find myself driving around in circles for a bit before I found the one tiny ramp I needed to get at a collectible hiding on the roof of a building at the other end of the map. That's not a challenge, merely a tedious detour in a game full of them. I was shocked when I beat the game to find that it had only taken me 5-ish hours to complete, because the lack of exciting challenges in the back end made it feel closer to eight or nine.

Bottom line, Yellow Taxi Goes Vroom is a kind-of neat idea without the level design to make it work. Get it on sale if you feel you must, but the 3D collect-a-thon is a relatively crowded genre, and finding something better wouldn't take too much work.
