Active steering technology is available in various luxury car brands such as BMW, Audi, Mercedes-Benz, and Lexus. These cars are equipped with active steering systems that can adjust the steering ratio and assist the driver in maneuvering the vehicle at different speeds. Active steering enhances driving dynamics, stability, and overall safety by providing more precise control and responsiveness. **

One good and affordable PC steering wheel available for under 200 euros is the Logitech G29. It offers a realistic driving experience with dual-motor force feedback and responsive pedals. The wheel is compatible with PC and PlayStation consoles, making it versatile for different gaming setups. Overall, the Logitech G29 is a popular choice among gamers for its quality and affordability. **

The correct grammar for "sure 638" and "sure 1689" would be "I am sure of 638" and "I am sure of 1689" respectively. The phrase "sure of" is used to indicate confidence or certainty in a particular number or statement. It is important to include the preposition "of" after "sure" to convey the intended meaning. **

Steering with a computer steering wheel like the Logitech G29 in racing games can feel quite realistic, especially when paired with a high-quality racing simulator setup. The force feedback and sensitivity of the wheel can closely mimic the feel of steering a real car, providing a more immersive experience. However, there are still differences in the physical feedback and G-forces experienced when driving a real car, which can make the experience of steering a real car more realistic. Overall, while steering with a computer steering wheel can provide a very realistic simulation, it may not fully replicate the experience of steering a real car. **

Power steering is a system in a vehicle that helps the driver steer the wheels more easily by using hydraulic or electric power to assist in turning the steering wheel. This system reduces the amount of effort required by the driver to turn the wheels, especially at low speeds or when the vehicle is stationary. Power steering makes it easier to maneuver and control the vehicle, and it has become a standard feature in most modern cars. **
