Are Portable Jump Starters Worth It, The Most Fuel-Efficient Speed to Drive, Timing Chains vs. Timing Belts

This week, we go through the mailbag and answer audience questions, including: Is driving 55 mph really more fuel-efficient—even in a 10-speed like the Acura TLX? We break down the science behind highway MPG, explain how regenerative braking affects brake light activation in EVs like the Hyundai Kona Electric, Hyundai Ioniq 5, and Kia Niro EV, compare jump-starting with cables vs. lithium battery boosters, dig into timing chain vs. timing belt replacement costs in models like the Honda CR-V, and help you decide whether to buy or lease a Honda Ridgeline. Plus, we highlight the best used cars for easier entry and exit, including the Toyota Crown and Subaru Crosstrek.
