Lisbon is connected by rail and road to the interior of Portugal and to the rest of Europe. The 1.5-mile- (2.4-km-) long 25th of April Bridge, one of the longest suspension bridges in western Europe, has served as the main roadway into the city since it was built in the mid-1960s.
NHTSA estimates that 73% of light vehicles already voluntarily will have rear-view cameras by the final deadline of 2018 and that the cost per vehicle to equip the remainder will be $132 to $142 for a complete system, $43 to $45 to add the camera to a vehicle that already has an adequate display screen.
1 The installation process, on the other hand, will cost around $75 to $300, depending on the setup. 2  However, you can save on the camera by installing it yourself, which is not difficult as most of the camera systems are sold with the installation instructions. Additional pieces of hardware such as wiring and harnesses may cost extra. 2  These parts should not cost more than $20. 3  If you have the type of backup camera that uses a screen rather than the rearview mirror, there are other features you can purchase.
