CVT vs. Automatic Transmission: Which Is Better? For most everyday commuters and many hybrids, a well-executed CVT (continuously variable transmission) is better for fuel efficiency and smooth, stop‑and‑go driving; for performance, towing, high-load use, and long-term durability under stress, a modern torque‑converter automatic is usually the better choice. The “best” option depends on how you …
Does a taxi meter go up in traffic? Yes—most taxi meters continue to rise in traffic because fares are typically calculated using a mix of distance and time. When a cab is moving slowly or stopped, the meter switches from charging per mile/kilometer to charging for “waiting time,” so the fare increases even if you …

Where Seatbelt Pretensioners Are Located Seatbelt pretensioners are typically located in one or more of three places: inside the belt retractor (usually in the B‑pillar or within the seat), inside the buckle assembly at the seat base, and sometimes at the outboard lap-belt anchor near the vehicle’s floor or sill. Exact placement varies by vehicle …
Brake Lights Not Working: Can You Be Pulled Over? Yes. In most jurisdictions, driving with one or more inoperative brake lights is an equipment violation that gives police lawful grounds to stop your vehicle. Officers can issue a warning or a citation because traffic codes typically require working stop lamps for safety; the exact requirements—how …
Can I still drive if my power steering goes out? Yes, most cars remain steerable without power assist, but the wheel becomes very heavy—especially at low speeds—making quick maneuvers difficult and increasing crash risk. The safest move is to slow down, signal, and pull over as soon as it’s safe, then arrange a tow. If …
How Occupant Detection Systems Work Occupant detection systems use a mix of sensors—such as weight and pressure pads, seat-buckle switches, cameras, infrared, and millimeter-wave radar—combined with algorithms that fuse data to determine whether someone is present, where they are, and in some cases who they are and what they’re doing; the results trigger safety features …
