Technology giant Google has patented a way of linking online ads to free or discounted taxi rides to the advertising restaurant, shop or entertainment venue.
The transport-linked ad service could encourage consumers to respond more often to location-based special offers, experts say.
Algorithms would work out the customer's location, the best route and form of transport, Google says.
Analysts have welcomed the idea.
Gregory Roekens, chief technology officer at advertising company AMV BBDO, told the BBC: "This is trying to turn advertising into a utility and remove barriers for consumers. It's a really interesting idea."Location-based
Advertisers will mine huge databases recording people's habits, likes and preferences so that ads can be highly targeted.
Combining this information with location data gleaned from wi-fi, cellular and GPS tracking will enable businesses to tailor their ads and special offers according to where people are, the time of day and their schedules.
The addition of free or cheap travel to the location will be the icing on the cake, Google hopes.
In August, Google's venture capital arm invested $258m in Uber, the San Francisco-based car hire network.
Mr Roekens believes Google is envisaging customers making use of such services when responding to mobile ads in future.
And given the company's major investment in autonomous vehicle technology, the prospect of customers being ferried automatically to nearby business venues after responding to location-based ads on their smartphones does not seem too fanciful.
