Rumble strip – Wikipedia

Rumble strips are controversial as they can have noise impacts on surrounding communities, and some people argue that the safety benefits of them are overstated. They also can be dangerous to cyclists if not properly planned and used, and cause problems with icing on roads.

Interstates Aren’t Unique

|

Many people think that each Interstate in America gets a unique number for the whole country. That is true within a state and within same region of the country, but nationally, some interstate numbers are reused.

Interstate 86 is both the number for the Southern Tier Expressway in New York and the I-84/I-15 connector in Idaho.

Interstate 88 is both the number for the Warren Anderson Expressway in New York and the Ronald Reagan Tollway in Illinois.

State DOT generally avoid having an interstate road overlap or cross with a similarly numbered US, state, or county highway — to avoid confusion.

Within New York there is one state highway (NY Route 90 in the Finger Lakes) that crosses the NY Thruway (I-90). There is no interchange between the two highways, and this is the only time within New York when this happens.

The Prisus’ Continuously Variable Transmission

Continuously Variable Transmission.

The Toyota Prisus' transmission is much more fascinating then you might think.

A constant velocity transmission or and a traditional transmission increases the gear ratio at lower speeds to allow the wheels to turn a smaller distance in comparison to the engine speed. This provides more torque to wheels help the engine overcome inertia of the car at low speeds.

The Prisus takes a different tack. The engine operates at a constant gear ratio, but to provide the additional torque needed to get the vehicle moving at low speed, it uses an electric motor to assist the gas motor at spinning the wheels.

It's a very cool concept!

ESC, strong roofs reduce but don’t eliminate all rollover injuries

"In nearly all of the 19 crashes of models with standard ESC, the rollovers were preceded by an impact. In other words, they were pushed over by another vehicle or they flipped after hitting an object. In contrast, 37 percent of the rollovers of vehicles without standard ESC weren't preceded by an impact, meaning in all likelihood they lost stability during a maneuver."

"There always have been rollovers caused by an initial impact, but since it is more difficult for ESC to address them, they will account for a larger proportion of the remaining rollovers as ESC becomes more common. Although they are more complex, rollovers of vehicles with ESC tend to be less severe. Only 9 percent of the crashes of models with standard ESC involved six or more quarter turns. In contrast, 41 percent of the rollovers of vehicles without standard ESC did."
