If you’ve ever fumbled around with your phone while in your car (hopefully not while driving!) and had a strong intuition that there must be a better, safer, and smarter way to use a phone in your car, then you were predicting the arrival of smartphone integration with Apple CarPlay and Android Auto.
These two respective applications take your handy smartphone and turn it into a bona fide smart car feature that integrates all of your apps, voice technology, and other useful smartphone features right into your vehicle’s electronics system. When you connect, a very familiar smartphone screen pops up on your car’s display with all of your apps ready to go.
One of the biggest incentives behind this technology is to give you a reason to put your phone down (if safety wasn’t enough of a reason!) and be able to access all its features using steering wheel buttons and voice activation. The hands-off accessibility of Apple CarPlay and Android Auto is being hailed as a revolutionary achievement in both car and phone technology which seamlessly integrates to give drivers a safer, more accessible, and technology-friendly driving experience.

Lifting provides many advantages for off-road use, including greater approach, breakover, and departure angles. The taller tires get the differential higher off the ground, reducing the risk of damage from obstacles, and all four wheels gain maximum traction due to the lifted suspension.
Taller tires mean greater visibility. Whether you’re venturing off the beaten path or commuting to work, the higher seating position makes it easier to see further down the road and over other vehicles. It’s a useful feature for detecting traffic jams early so you can take a detour to avoid them.
Enhanced towing capability. A lifted truck can provide a better safety margin and weight advantage against the offending load when towing, as Truck Trend Network confirms. This means that you can tow heavier and larger loads without worrying about the truck swerving during the drive.
Better off-roading performance. If you’re passionate about off-roading, then lifting your truck is a great choice. The most obvious benefit is the increased ground clearance when driving over rugged terrain, which reduces the risk of damage to your undercarriage. Additionally, the larger tires of a lifted truck are designed to flex around obstacles like large rocks, which translates to more tire-to-ground contact for greater traction.

Highest Recommendation”
