* The law: Speed limits are in place for a reason. Driving above the posted speed limit is illegal and can result in fines, license suspension, or even jail time. Different areas have different speed limits, and exceeding them puts yourself and others at risk.
* Road conditions: Weather (rain, snow, ice), road surface (wet, dry, construction), and visibility all affect safe driving speeds. Driving fast in poor conditions is incredibly dangerous.
* Your driving skills and experience: Even if the law allows a certain speed and the conditions seem fine, your own abilities and experience determine whether you can safely handle driving at that speed. New drivers, in particular, should avoid high speeds.
* Your car's capabilities: While your car might *be capable* of high speeds, that doesn't mean it's *safe* to drive it at those speeds. Consider your car's handling, braking, and tire capabilities.
In short, you *can* drive your new car fast within the bounds of the law, on suitable roads, and only if you possess the necessary skills and experience. However, prioritizing safety should always come first. Driving at a safe speed is more important than driving fast.
