In one sentence, describe what the following article is about: Braking suddenly, accelerating quickly, and navigating around other cars all cost you speed. Being aware of the track can help you plan your moves so you can keep your momentum going. Keep your eyes on the track ahead of you so you can adjust your speed as needed and plan the best route down the track.  For instance, you might need to suddenly hit the brakes if you drive up on a packed track. Once you pass the other cars, you might hit your accelerator. This slows you down. Instead, you might see that there’s a traffic jam up ahead and slow down slightly. Then, you might loop around the other cars and return to your previous speed. A straight path means that you aren’t weaving in and out of the other cars. You can maintain your highest speed when you’re going straight, so pick the lane that’s most empty. It’s okay to change lanes as you go around the track, but do your best to stay on the same path. This means it may be faster to drive in the outer lane sometimes, even though it’s a greater distance. You might be tempted to slam on the accelerator as soon as you get the signal to go, but this usually slows down your time. Instead, accelerate gradually as you enter your first lap. Then, increase your speed with each lap to build and sustain your momentum. This helps you approach the finish line strong.  Your go kart won’t hit its highest speeds when you rev the engine. It’s better to gradually build speed. This also helps you slowly pass the other karts instead of having to constantly brake and accelerate as you all start the race. While many go karts have a wide rubber bumper to protect you, bumping into objects slows you down. Keep a distance from curbs and barriers so you don’t scrape or slam against them. Additionally, don’t get too close to other karts, as you might accidentally crash into them. Some people like to give slower carts that are blocking the track a gentle bump to encourage them to move out of the way. However, this will slow you down. It’s better to just go around them if you can. To take the corners faster, move to the outer lane of the track just before you get to the corner. Then, cross the corner in a straight line from outer corner to outer corner, cutting close to the inside of the track as you pass the curve. If you dart from outer corner to outer corner, you'll be able to drive across the curve in a straighter line compared to if you hug the curve. You'll still need to turn your go kart, but the angle of the turn won't be as sharp, which allows you to better maintain your speed.
Summary:
Watch the track ahead of you so you don’t have to slow down. Stay on a straight path so you can maintain your speed. Increase your speed on each lap to slowly build your speed. Be careful that you don’t hit curbs, barriers, or other go karts. Go wide on the corners, then cut in toward the inside of the track.
