Asked what he means by "real driver", the French Canadian explained: "Well, all you have to do is listen to what other drivers have said about his decision".
Although practice for the coveted event does not officially start until the May 15 with the rookie orientation programme, Alonso has been offered a chance to acclimatise to oval racing.
LEEDS, Alabama:IndyCar drivers will throw out the welcome mat for Fernando Alonso on his Indianapolis 500 debut next month but have warned the double Formula One champion not to expect any support on the track. Any initial sense of politeness about Honda's turd of an engine in the too-slow, too-fragile McLaren has long disappeared from Alonso's mouth even out of the vehicle, and that brutal honesty only gets turned up to 11 on the team radio.
"So after, you know, a successful F1 championships, I think the opportunity to race in Indy 500, the opportunity to race one day in the future in Le Mans, that dream of the Triple Crown, winning all the Big Three, is something very attractive for a driver point-of-view".
Earlier this month, McLaren had announced that they would return to the Indianapolis 500, using Honda engines after an absence of almost 38 years.
While Ricciardo says he "wouldn't want to miss Monaco", he thinks 35-year-old Alonso has picked a good window to branch out.
Earlier this month McLaren announced that they would run Alonso in the 101st Indianapolis 500, featuring a joint entry with Honda and Andretti Autosport.
Alonso, who is yet to finish a race with McLaren this season due to a series of reliability issues, will skip this year's Monaco Grand Prix to race in the Indy 500. Andretti Autosport's Ryan Hunter-Reay won "The Greatest Spectacle in Racing" in 2014. Alonso will be on hand for the IndyCar Grand Prix of Alabama.
Fans can watch the entire Alonso test free of charge from the Turn 2 viewing mounds, IMS Museum parking lot and South Terrace Grandstand. McLaren's doing all it can to stop that from happening - but is letting him contest the Indianapolis 500 a sign things are going too far? "He has really good teammates", Montoya said.
"But I didn't think that it was possible to attempt until I was retiring from F1". Pigot, of Orlando, Fla., is the 2015 Indy Lights champion and winningest driver in the Mazda Road to Indy driver development program.
