Putting their money behind their mouths, a pair of Tesla Model S owners took out an ad in the Palo Alto Daily and Weekly that drew the attention of Tesla CEO Elon Musk for the spot's praise and critiques of the automaker's electric vehicles.

The ad characterized the cars as fun and reliable vehicles that deliver a "phenomenal driving experience." But the ad from the two "highly satisfied Tesla owners" in New York also recommended changes to enhance the vehicle's safety, convenience and marketing.

The ad, in calling for safety enhancements, asked for a system to monitor blind spots, cross traffic and low objects. Sound sensors could be employed to apprise drivers of objects near the front or rear of the EVs, the ad suggested.

The ad also called for a voice-dialing feature and the dedication of a larger area of the EVs' touch screen for answering phone calls.

For convenience, the ad requested that the cup holder are brought in closer to passengers and that power charging caps would auto-close after unplugging power cords. The ad also called for a rework of the sun visor to better accommodate short drivers as well as a redesign of the center console to project the Tesla image.

Rounding out the list of requests, the ad asked for Telsa to step up its promotion of its EVs.

"People are fascinated by my Tesla and my wife's Tesla," the ad stated. "Promotion of your cars to the general public could only have a positive effect, creating many additional enthusiastic Tesla owners."

Musk stated on Twitter that many of the changes recommended in the Palo Alto ad will rolled out soon, though he offered no clue as to which suggests the EV maker would follow up on with revisions.

With Tesla Motors' patents now all open-source, the automaker has spawned the development of other EVs. Saleen Automotive recently launched the 4sixteen, an EV based on Telsa's Model S, at a car show in Pebble Beach, Calif.

While Tesla initially fought to protect its technology from vultures, it now encourages other automakers to make use of its EV patents. The EV maker said the sharing of its patents was a response to the auto industry's timidity in embracing EVs, because it couldn't produce enough EVs on its own.

"Our true competition is not the small trickle of non-Tesla electric cars being produced, but rather the enormous flood of gasoline cars pouring out of the world's factories every day," stated Tesla Motors in a press release.
